The problem of finding the molecular weight of liquids is a difficult one, for very little is known of the nature of liquids. A liquid is defined as a substance which has a definite volume but no definite shape. This statement establishes the main difference between a liquid and a gas on the one hand, and between a liquid and a solid on the other.

We draw an analogy from the study of gases and say that we believe that liquids consist of molecules moving in straight lines and a so about their axes. We assume that the molecules of a liquid move amongst themselves with comparative ease and so account for the fact that a liquid fills completely the bottom of any containing vessel. We also assume that the molecules of a liquid are close enough together to exert a mutual attraction in excess of the energy of motion in straight lines. This, we suppose, restrains them from flying apart and filling completely any containing space, as does a gas. The study of liquids furnishes no regularities nor generalities as the gas laws.
