    Solid expand on heating because particles of matter loose there original configuration due to thermal energy provided in the form of heating radiation and expand due to vibrational motion of particles in a series. but there are some exceptional property of solid like regalation . ------------------------------------------------------------------------------ Air expands on heating. Why does this happen? It is because the particles of air on becoming warm, move away from each other and take up more space. So we can say that air on becoming hot occupies more space. Since the particles move away from each other, the air becomes less dense and lighter in weight.
