THE difficulty of reconciling line spectra with the kinetic theory of gases, has been referred to by Prof. Fitzgerald (NATURE, January 3, p. 221). The following considerations show that it is ...

The kinetic particle model explains the properties of the different states of matter. Particles in solids, liquids and gases have different amounts of energy. The particles are arranged ...

This step looks at the behaviour of a fixed quantity of gas under varying pressure, volume and temperature. The kinetic theory model can be used to explain the properties of solids, liquids and ...
