Solids, liquids and gases

An investigation into the three states of matter.

Lawrence Bragg begins by illustrating the different forms that water can assume, showing how these change in form depending on changes in temperature. This is followed by a comparison of the three divisions of matter, proceeding to a discussion of latent heat and pressure. Each topic, simply described in terms of atoms and molecules, is supplemented by a vivid demonstration.
