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

LawPV = nRT

Governing equation

P V = N k_{B} T, N = 120, T = 3.0

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