in a cold and hot water). That leads us to the conclusion. The intensity of the molecular motion is proportional to the temperature. The proofs of the third assumption are. The existence of the elastic force. It means that when the distance between two molecules decreases they repel one another. When the distance between two molecules increases There are some basic assumptions that are made by this theory. They are: 1. A macroscopic volume contains a large number of these tiny particles.
