1. What is the Ideal Gas Law?

The Ideal Gas Law describes the relationship between pressure, volume, temperature, and amount of an ideal gas. It provides a fundamental equation for calculating gas properties under various conditions.

2. How Does the Calculator Work?

The calculator uses the Ideal Gas Law equation:

Where:

• \( V \) — Volume (L)
• \( n \) — Amount of substance (mol)
• \( R \) — Gas constant (0.0821 L·atm/mol·K)
• \( T \) — Temperature (K)
• \( P \) — Pressure (atm)

Explanation: The equation shows that volume is directly proportional to the amount of gas and temperature, and inversely proportional to pressure.

3. Importance of Volume Calculation

Details: Calculating gas volume is essential in chemical reactions, industrial processes, environmental studies, and laboratory experiments involving gases.

4. Using the Calculator

Tips: Enter amount in moles, temperature in Kelvin, and pressure in atmospheres. All values must be positive and non-zero.

5. Frequently Asked Questions (FAQ)

Q1: What is an ideal gas?
A: An ideal gas is a theoretical gas that follows the ideal gas law exactly, with no intermolecular forces and particles that occupy no volume.

Q2: When is the ideal gas law applicable?
A: It works well for most gases at low pressures and high temperatures, but becomes less accurate at high pressures and low temperatures.

Q3: How to convert Celsius to Kelvin?
A: Add 273.15 to the Celsius temperature: K = °C + 273.15

Q4: What are the units for the gas constant R?
A: R = 0.0821 L·atm/mol·K for these units. Other common values include 8.314 J/mol·K and 62.3637 L·torr/mol·K.

Q5: Can this calculator be used for CO₂ specifically?
A: Yes, but CO₂ deviates from ideal behavior at high pressures and low temperatures due to intermolecular forces.
