Loi des Gaz Parfaits

How to use it

1. Given: P=202650 Pa, V=0.m³, n=1.mol, T=0 (unknown)
2. Rearrange: T = PV ÷ (nR)
3. Calculate: T = (202650 × 0.015) ÷ (1.2 × 8.314)
4. T = 3039.÷ 9.9768 ≈ 304.68 K

Common mistakes

• ⚠️ Not setting exactly one variable to for solving
• ⚠️ Using wrong value for gas constant R
• ⚠️ Using Celsius instead of Kelvin for temperature

Worked example

Find the missing variable (T=0) in ideal gas law with P=202650 Pa, V=0.m³, n=1.mol.

The missing variable is calculeted: {missing} using PV = nRT where R = 8.314 J/(mol·K).
