Physics Tool
Ideal Gas Law Calculator
The equation of state of a hypothetical ideal gas (PV = nRT).
Calculated P
1.0007 atm
Σ The Formula
PV = nRT
Real World Examples
STP Condition
1 mole of gas at 273.15K and 1 atm occupies ~22.4 Liters.
Compression
Halving the volume at constant temperature doubles the pressure (Boyle's Law).
# About This Calculator
The Ideal Gas Law describes the behavior of gas particles under various conditions of pressure, volume, temperature, and amount of substance.
Variables:
- P: Pressure (in atmospheres).
- V: Volume (in liters).
- n: Number of moles.
- T: Temperature (in Kelvin).
- R: Idea gas constant (0.08206 L⋅atm/mol⋅K).
How To Use
- Choose the variable you want to **Solve For**.
- Enter the values for the other three variables.
- Ensure temperature is in **Kelvin** (K = °C + 273.15).
- The result is updated instantly with the correct unit.
Frequently Asked Questions
What is an 'Ideal' gas?+
A gas where particles do not attract/repel each other and occupy zero volume. Real gases behave mostly like ideal gases at high temperatures and low pressures.
