Gas Laws
Change a container and watch a microscopic model become pressure.
Follow the cause1 / 3
Particles collide with the container. Pressure is the macroscopic result of microscopic momentum transfers at the walls.
idealized particle modeln, R constant
temperature50 K
volume62%
relative pressure81
At 50 K and 62% of the reference volume, the ideal model reports a relative pressure of 81. Temperature changes collision energy; volume changes collision frequency.
A gas is represented here as moving particles. It is a useful model, not a literal picture of what a gas looks like; real gases add attractions, finite particle volume, and non-equilibrium effects.
