Noun
(physics) a theory that gases consist of small particles in random motion
Source: WordNetAccording to the kinetic theory of gases, the mean kinetic energy of a molecule is a measure of absolute temperature. Wilhelm Wien
For example, in the introduction to his 1947 book "Kinetic Theory of Liquids", citation Yakov Frenkel proposed that "The kinetic theory of liquids must accordingly be developed as a generalization and extension of the kinetic theory of solid bodies. Source: Internet
He wrote a paper called "Theory of Gases," in which he outlined the basis of the kinetic theory of gases, but after submitting it to the Russian Physico-Chemical Society (RPCS), he was informed that his discoveries had already been made 25 years earlier. Source: Internet
It can also be derived from the kinetic theory of gases: if a container, with a fixed number of molecules inside, is reduced in volume, more molecules will strike a given area of the sides of the container per unit time, causing a greater pressure. Source: Internet
The confirmation of Einstein's theory constituted empirical progress for the kinetic theory of heat. Source: Internet
The kinetic theory in turn led to the statistical mechanics of Ludwig Boltzmann (1844–1906) and Josiah Willard Gibbs (1839–1903), which held that energy (including heat) was a measure of the speed of particles. Source: Internet
