A picture of a gas of hard-sphere molecules. The temperature of the gas is a measure of the average energy of the molecules as they move and collide in the box. Here, the size of helium atoms relative to their spacing is shown to scale under 136 atmospheres of pressure. These room-temperature atoms have a certain, average speed (slowed down here a trillion fold).
