1 Answer

Answer :

The kinetic theory of gas is also called kinetic-molecular theory. The theory that scientists have proposed regarding the molecular and molecular motion or velocity of gas is known as the kinetic-molecular theory of gas. How many of these theories are acceptable? The acknowledgments are the product of the research of scientists such as Bernoulli, Kronig , Clausius , Maxwell , 1860, Kelvin , Boltzman , 1868 . In fact , Bernoulli and Cronig were initially interested in explaining the behavior of gas. Scientists Maxwell and Kelvin modernized their kinetic model.
