🔍 What Is the Ideal Gas Law?
The Ideal Gas Law is a fundamental equation in thermodynamics:
PV = nRT
Where:
- P = pressure of the gas
- V = volume of the gas
- n = number of moles of gas
- R = ideal gas constant (0.0821 L·atm/mol·K)
- T = temperature in Kelvin (K)
This law describes the behavior of an “ideal” gas—an approximation that works well under many real-world conditions.
🧮 How Does the Ideal Gas Law Calculator Work?
You simply input any three of the following variables:
- Pressure (P)
- Volume (V)
- Moles (n)
- Temperature (T)
The calculator then solves for the missing value using the rearranged Ideal Gas Law.
Example:
- Pressure = 1 atm
- Volume = 22.4 L
- Temperature = 273 K
- Solve for n:
-
n = PV / RT = (1 × 22.4) / (0.0821 × 273) ≈ 1 mol
