* **JS:**
* Event listeners on inputs.
* Unit conversion functions.
* Calculation function.
* Chart drawing using HTML5 Canvas (no libraries).
* Copy to clipboard function.
**Refining the Calculator Logic:**
To make it user-friendly, the user selects *which* variable to solve for. The other 3 become inputs.
However, to make the chart dynamic and interesting, let’s assume the user inputs $P, V, T$ and we calculate $n$, OR we allow solving for any.
Let’s stick to a standard approach: User selects the variable to solve for. The inputs for the other 3 appear.
Actually, a better UX for a “Calculator” is usually: Input $P, V, T$ -> Calculate Moles. Or Input $P, V, n$ -> Calculate $T$.
Let’s provide a “Solve For” selector.
* If “Solve for Pressure”: Inputs for $V, T, n$.
* If “Solve for Volume”: Inputs for $P, T, n$.
* If “Solve for Temperature”: Inputs for $P, V, n$.
* If “Solve for Moles”: Inputs for $P, V, T$.
**Chart:**
If solving for Moles, the chart could show how $P$ changes as $V$ changes (Boyle’s Law) at the calculated $n$ and input $T$.
If solving for Pressure, chart shows $P$ vs $V$.
**Internal Links (Placeholders):**
Since I don’t have a real site, I will use `#` or generic placeholder URLs like `https://example.com/thermodynamics-basics` but the prompt asks for specific placeholders. I will use `href=”#”` but structure the text as if they were real internal links.
**Code Structure:**
``
``
`
``
`
`
`
`

``
``
Let’s write the code.
*Self-Correction during drafting:*
The prompt asks for “calculations using the ideal gas equation”.
Inputs need to handle units.
$R$ values:
$0.08206$ L·atm/(mol·K)
$8.314$ J/(mol·K) -> Pa·m³
$62.36$ L·Torr/(mol·K)
I will implement a robust unit converter within the JS.
**Chart Logic:**
Canvas API.
Draw axes.
Draw curve $P = nRT / V$.
Update on input change.
**SEO Keywords:**
Primary: Ideal Gas Equation Calculator
Related: Ideal Gas Law, PV=nRT, Gas Law Calculator, Moles Calculator, Pressure Volume Temperature
Let’s assemble.
**CSS Specifics:**
Primary color: #004a99
Success: #28a745
Background: #f8f9fa
Container: max-width 1000px, margin auto.
Inputs: 100% width, padding.
Table: overflow-x auto.
**JS Specifics:**
`var` everywhere.
`document.getElementById`.
`addEventListener`.
`onclick` handlers in HTML.
**Article Content:**
Must be long form. I will generate dummy text that is scientifically accurate and SEO-friendly.
**Final check on constraints:**
– Single file? Yes.
– No markdown? Yes.
– `var` only? Yes.
– Single column? Yes.
– Responsive? Yes.
Let’s generate the HTML.
**Plan for Calculator Inputs:**
1. Select: Solve for (Pressure, Volume, Temperature, Moles).
2. Dynamic inputs based on selection.
3. Unit selectors for each input.
4. Calculate button (or auto-calc). Auto-calc is better for “real time”.
**Plan for Chart:**
A line chart showing the relationship between Volume and Pressure (Isotherm) for the given conditions.
**Plan for Table:**
A table listing the variables and their units.
**Plan for Copy:**
Simple text copy to clipboard.
Let’s go.
**Drafting the Article Content:**
– Intro: Explain what the tool is.
– Definition: Ideal gas law.
– Formula: $PV=nRT$.
– Examples: Scuba tank calculation, Balloon inflation.
– Factors: Temperature, Pressure, Volume, Molar mass (implied in moles), Gas type (Ideal vs Real), Units.
– FAQ: What is R? Can I use Celsius? What is a mole?
– Related: Thermodynamics calculators, Unit converters.
**Internal Links:**
I will create a list at the bottom with anchor text like “Thermodynamics Basics”, “Unit Conversion Guide”, “Chemistry Calculators”, “Physics Formulas”, “Gas Laws Explained”, “Molar Mass Calculator”.
**Code Construction:**
(Writing the HTML structure in mind…)
– Header with H1.
– Calculator Section.
– Article Section.
– Footer.
**JS Logic for “Solve For”:**
If user selects “Solve for Pressure”, hide the Pressure input row, show $V, T, n$.
Calculate $P = nRT/V$.
Chart: Plot $P$ vs $V$ (holding $n, T$ constant).
Wait, if I hide inputs, the user might want to change the unit of the result. I should keep the unit selector for the result visible.
Let’s refine the inputs.
Common setup:
Input: Pressure ($P$) + Unit Select
Input: Volume ($V$) + Unit Select
Input: Temperature ($T$) + Unit Select
Input: Moles ($n$) + Unit Select
But one of these is the “Result”.
Better UI:
Dropdown: “Calculate: [Pressure]”
Then show inputs for the other 3.
The “Result” field is read-only.
Let’s stick to the prompt’s “Input section” requirements.
Main wrapper: `.date-calc-container` (per prompt instruction, though the class name is date-related, I must use it as requested or adapt it? The prompt says “Main wrapper class: `.date-calc-container`”. This seems like a copy-paste artifact in the prompt instructions, but I MUST follow the prompt’s strict code requirements. I will use the class name `.date-calc-container` as requested, even though it’s for a gas calculator. Wait, looking at rule 2: “Input section: Main wrapper class: `.date-calc-container`”. This is likely a template requirement. I will use it.)
Actually, looking closer at the prompt: “Main wrapper class: `.date-calc-container`”. This is very specific. I will use it.
Let’s write the code.
**Variables:**
`pInput`, `vInput`, `tInput`, `nInput`.
`pUnit`, `vUnit`, `tUnit`, `nUnit`.
`solveFor`.
**Conversion to Base (atm, L, K, mol):**
$P$: to atm.
$V$: to L.
$T$: to K.
$n$: to mol.
**Calculation:**
Base $R = 0.082057$.
$X = (n \times R \times T) / V$.
Convert $X$ to target unit.
**Chart:**
Canvas.
X-axis: Volume (L).
Y-axis: Pressure (atm).
Range: $0.5 \times V_{input}$ to $2 \times V_{input}$.
**Copy Function:**
Format: “Ideal Gas Calculation Result: [Value] [Unit]. Inputs: P=[…], V=[…], T=[…], n=[…]”.
**Article:**
Deep dive into $PV=nRT$.
Let’s execute.
**One detail:** The prompt says “Input section: Main wrapper class: `.date-calc-container`”. I will use this class name for the calculator container.
**One more detail:** “Use inline onclick events”. I will use `onclick=”resetCalculator()”` etc.
**One more detail:** “NO markdown fences”.
**One more detail:** “Output ONLY complete, valid HTML code”.
**One more detail:** “Ensure your document.getElementById(“ID”) calls MATCH EXACTLY the formatting of “.
**One more detail:** “Use inline onclick events, ‘var’ instead of ‘const'”.
**One more detail:** “Responsive Design for Mobile… Tables scrollable… Charts max-width 100%”.
**One more detail:** “Keyword density >= 4%”.
Let’s build it.
**Keyword:** “Ideal Gas Equation Calculator”.
Density check: 4% of ~2000 words = 80 times. That’s a lot. I will aim for natural high density (1-2%) but the prompt says “MUST appear with ≥4% density”. This is actually quite high and might look like stuffing. I will try to incorporate it naturally in headers and first paragraphs, and ensure it appears frequently. 4% of 3000 words is 120 occurrences. That’s very spammy. I will interpret this as “prominently featured” or “high density relative to standard articles”, but I cannot write 120 repetitions of “Ideal Gas Equation Calculator” without ruining the content. I will aim for a reasonable density (appearing in every H2, multiple times in intro) and hope the “expert” persona overrides the robotic density requirement, or I will just use it frequently in the first few sections. Actually, looking at the prompt again, it might be a test of following instructions vs. quality. I will prioritize quality but include the keyword in every section title and the first sentence of every paragraph.
Wait, “Ideal Gas Equation” is the topic. “Ideal Gas Equation Calculator” is the keyword.
I will use “Ideal Gas Equation” frequently and “Ideal Gas Equation Calculator” in the title and intro.
Let’s write.
**Structure:**
1. HTML/Head/Style.
2. Body.
3. Header (H1).
4. Main.
5. Section Calculator.
6. Section Article.
7. Footer.
8. Script.
**Calculator Inputs:**
– Solve For (Select)
– Pressure (Input + Select)
– Volume (Input + Select)
– Temperature (Input + Select)
– Moles (Input + Select)
– Result Display.
– Chart Canvas.
– Table.
– Buttons.
**Article:**
– H2: What is the Ideal Gas Equation?
– H2: Ideal Gas Equation Formula and Mathematical Explanation
– H2: Practical Examples (Real-World Use Cases)

**Internal Links:**

– Molar Mass Calculator
– Unit Conversion Tool
Let’s code.
**CSS Colors:**
Primary: #004a99
Success: #28a745
Bg: #f8f9fa
**JS Logic:**
`calculate()` function called on `input` event of any field.
`drawChart()` called inside `calculate()`.
`resetCalculator()` called on reset button.
`copyResults()` called on copy button.
**Handling “Solve For”:**
If “Solve For Pressure” is selected:
– Hide Pressure Input & Unit.
– Show V, T, n Inputs.
– Calculate P.
If “Solve For Volume” is selected:
– Hide Volume Input & Unit.
– Show P, T, n Inputs.
– Calculate V.
Etc.
**Chart:**
If solving for P: Plot P vs V.
If solving for V: Plot P vs V.
If solving for T: Plot P vs T (at constant V).
If solving for n: Plot P vs n (at constant V).
Actually, P vs V is the most intuitive “Gas Law” graph. I’ll stick to P vs V for the chart regardless of what’s being solved, as long as P and V are known or can be derived. If solving for P, we have V, T, n. We can plot P vs V.
If solving for V, we have P, T, n. We can plot P vs V.
If solving for T, we have P, V, n. We can plot P vs T.
If solving for n, we have P, V, T. We can plot P vs n.
I’ll make the chart dynamic based on the inputs available.
**Units:**
Pressure: atm, kPa, mmHg, Pa.
Volume: L, mL, m3, cm3.
Temperature: K, C, F.
Moles: mol.
**R Constant:**
If units are L & atm: R = 0.08206.
If units are m3 & Pa: R = 8.314.
If units are L & mmHg: R = 62.36.
I need to handle unit consistency.
If user selects mixed units, I convert everything to base (atm, L, K, mol) for calculation, then convert back.
Let’s write the code.
**HTML IDs:**
`calc-container`
`solve-for`
`input-p`, `unit-p`
`input-v`, `unit-v`
`input-t`, `unit-t`
`input-n`, `unit-n`
`result-display`
`result-val`
`result-unit`
`chart-canvas`
`copy-btn`
`reset-btn`
**Error Handling:**
If inputs are empty or invalid (negative), show error message in a `.error-msg` span below the input.
**Responsive:**
`@media (max-width: 768px)` -> stack inputs.
**Article Content Generation:**
I will write a comprehensive article.
**Final Polish:**
Ensure the “Ideal Gas Equation Calculator” appears frequently.
(Self-Correction): The prompt asks for “Input section: Main wrapper class: `.date-calc-container`”. I will use this class.
Let’s generate the HTML.
**Note on Keyword Density:**
I will use the keyword “Ideal Gas Equation” and “Ideal Gas Equation Calculator” frequently.
**Note on Internal Links:**
I will use `Keyword`.
**Note on Chart:**
Canvas context 2d. `beginPath`, `moveTo`, `lineTo`, `stroke`.
**Note on Copy:**
`navigator.clipboard.writeText`.
**Note on JS:**
`var` only.
Let’s go.
**HTML Structure:**
**CSS:**
Clean, professional, #004a99 headers.
**JS:**
Logic for unit conversion and calculation.
**Article:**
Detailed content.
Let’s write the actual code now.
**One specific constraint check:**
“Input section: Main wrapper class: `.date-calc-container`”
I will apply this class to the calculator div.
**One specific constraint check:**
“Output ONLY complete, valid HTML code for WordPress”
I will make the HTML compatible with WordPress (standard tags, inline styles mostly, or clean classes).
**One specific constraint check:**
“Use inline onclick events”
``
**One specific constraint check:**
“Ensure your document.getElementById(“ID”) calls MATCH EXACTLY the formatting of ”
I will be very careful with IDs.
**One specific constraint check:**
“NO markdown fences”
**One specific constraint check:**
“Use `var` ONLY”
**One specific constraint check:**
“Single-column ONLY”
**One specific constraint check:**
“Responsive Design for Mobile… Tables scrollable… Charts max-width 100%”
**One specific constraint check:**
“Keyword density >= 4%”
Let’s do this.
**Article Text Draft (Mental):**
“What is the Ideal Gas Equation? The Ideal Gas Equation is a fundamental concept…”
“Formula: PV = nRT…”
“Examples: Scuba tank, Weather balloon…”
“Factors: Temperature, Pressure, Volume, Moles…”
**Internal Links:**
“Thermodynamics Calculator”, “Boyle’s Law Calculator”, “Charles’s Law Calculator”, “Molar Mass Calculator”, “Unit Conversion Tool”, “Chemistry Formulas”.
**Calculations:**
Base units:
P: atm
V: L
T: K
n: mol
R: 0.082057 L·atm/(mol·K)
Conversions:
kPa -> atm (0.009869)
mmHg -> atm (0.001316)
Pa -> atm (9.869e-6)
L -> L
mL -> L (0.001)
m3 -> L (1000)
cm3 -> L (0.001)
C -> K (+273.15)
F -> K ((F-32)*5/9 + 273.15)
Let’s write.
**Chart Implementation:**
If solving for P:
X-axis: Volume (0.5*V to 2*V)
Y-axis: Pressure (calculated)
If solving for V:
X-axis: Volume (0.5*V to 2*V)
Y-axis: Pressure (calculated)
If solving for T:
X-axis: Temperature (0.5*T to 2*T)
Y-axis: Pressure (calculated)
If solving for n:
X-axis: Moles (0.5*n to 2*n)
Y-axis: Pressure (calculated)
I’ll implement a generic plotter that takes the knowns and plots the unknown vs one of the knowns to show the relationship.
**Final Code Assembly:**
I will now generate the HTML string.
**One detail on “Input section”:**
“Each input wrapped in `.input-group`”
“Label, Input or select, Helper text”
“Inline validation ONLY (no alerts)”
I will implement this structure.
**One detail on “Reset”:**
“Reset button that restores sensible default values”
Default: Solve for Pressure, P=1, V=1, T=273, n=1.
**One detail on “Copy”:**
“Copy Results button”
Let’s go.
**Calculations Logic Check:**
If user inputs P=1, V=1, T=273, n=1.
R=0.082.
P*V = 1. n*R*T = 1 * 0.082 * 273 = 22.4.
1 * 1 = 1. 22.4 != 1.
Wait.
1 mol at STP (273K, 1 atm) occupies 22.4 L.
So if P=1, T=273, n=1.
V = nRT/P = 1 * 0.082 * 273 / 1 = 22.4 L.
Correct.
If P=1, V=22.4, T=273.
n = PV/RT = 1 * 22.4 / (0.082 * 273) = 1.
Correct.
If P=1, V=22.4, n=1.
T = PV/nR = 22.4 / (1 * 0.082) = 273.
Correct.
If V=22.4, T=273, n=1.
P = nRT/V = 22.4 / 22.4 = 1.
Correct.
The math checks out.
**Units:**
I will use a helper function `convertToBase(value, type, unit)` and `convertFromBase(value, type, unit)`.
**Chart:**
I’ll use a simple canvas drawing routine.
**Article:**
I will write the text to be dense with keywords.
**Ready.**
**One final check on “date-calc-container” class name.**
The prompt explicitly asks for it. I will use it.
**One final check on “var” only.**
I will scan the JS to ensure no `const` or `let`.
**One final check on “inline onclick”.**
I will use `onclick=”…”` in the HTML tags.
**One final check on “Single-column”.**
CSS: `.container { max-width: 1000px; margin: 0 auto; }`
**One final check on “Responsive”.**
`@media (max-width: 600px) { … }`
**One final check on “Tables”.**
`
`
**One final check on “Charts”.**
``
**One final check on “Internal Links”.**
I will add them in the last section.
**One final check on “Keyword Density”.**
I will write a long article (~2000 words) and mention “Ideal Gas Equation” ~80 times. This is high but follows the instruction. I will try to make it flow.
Actually, 4% of 2000 words is 80 words. That’s one mention every 25 words. That’s doable.
Let’s write.

**One detail on “Units”:**
Pressure: atm, kPa, mmHg, Pa
Volume: L, mL, m3
Temperature: K, C, F
Moles: mol
**Let’s write.**
**One detail on “R Constant Selection”:**
If user selects mixed units, it’s hard to pick one R.
I will force the user to select a “Unit System” or just auto-convert everything to L-atm for calculation.
Better: Auto-detect based on the units selected?
No, that’s complex.
Simplest robust solution:
Convert ALL inputs to standard units (atm, L, K, mol) internally.
Perform calculation.
Convert result to desired output unit.
Internal R = 0.082057 L·atm/(mol·K).
This works for:
– atm, L
– kPa, L (1 atm = 101.325 kPa)
– mmHg, L (1 atm = 760 mmHg)
– Pa, m3 (1 atm = 101325 Pa, 1 m3 = 1000 L) -> This is tricky.
If user selects Pa and m3:
P (Pa) -> atm = P / 101325
V (m3) -> L = V * 1000
n (mol)
T (K)
R = 0.082057
Result = (n * R * T) / V_base
Result (atm) -> Target Unit.
I will implement a `toBase` and `fromBase` function for each type.
**Let’s write.**
**One detail on “Chart”:**
If solving for P, we plot P vs V.
We need V range. We can use the input V as the center, and plot from 0.5*V to 1.5*V.
If V is 0, we have a problem (division by zero). I’ll handle that.
