For example, the collisions caused by a gas trapped inside a balloon cause forces to act outwards in all directions, giving the balloon its shape.

A single particle does not have the properties ... close Brownian motionThe random motion of microscopic particles suspended in a gas or liquid as a result of collisions. In this example, the ...
