Recent investigations have made the kinetic theory of fluids one of the most vital branches of theoretical physics. Experimental progress has gone hand in hand with the development of theory.

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 ...

Boyle carried out an experiment that gave one of the first pieces of experimental evidence for the particle theory ... temperature of the gas increases, the particles gain kinetic energy and ...

It consists of a fully ionized or partially ionized gas, containing ions, electrons and neutral atoms. At present, thermonuclear fusion is the main area of research in plasma physics.

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 ...
