Gas in a Box — Kinetic TheoryLive

Controls

Pressure emerges from molecules hammering the walls. More particles or higher temperature → higher pressure, exactly as PV = nRT predicts.

Presets

▶ Run in Python

Data Inspector

Particles120
Temperature3.0
Pressure (wall)0
LawPV = nRT

Governing equation

Reading this result: Pressure scales with both particle count and temperature: doubling either roughly doubles the force on the walls (P ∝ nT).
