Ideal gas picture and pressure

Two gas containers before and after slow compression showing the same particle speeds but more wall collisions and higher pressure in the smaller volume, plus a wall collision with momentum change labelled

An ideal gas is a model in which particles are far apart, move randomly, and take up negligible volume compared with the container. Collisions are treated as perfectly elastic, with negligible forces between particles except during the brief collisions.
