It models the properties of matter in terms of continuous random motion of molecules. The temperature of gases is proportional to the average translational kinetic energy of molecules. Hence, the typical speed of gas molecules vrm is proportional to the square root of the temperature and inversely proportional to the square root of the molecular mass.

(In fact, we will take two averages: one over time to get the average force exerted by one molecule with a given velocity, and then another average over molecules with different velocities.) This approach was developed by Daniel Bernoulli (1700–1782), who is best known in physics for his work on fluid flow (hydrodyn…
