In this article we will discuss the concepts of intermolecular forces and Brownian motion, as well as how they relate to kinetic molecular theory. We’ll also talk about the Maxwell distribution of molecular velocities. These concepts will help you understand the fundamental concepts of thermodynamics. Brownian motion Brownian motion is an important part of kinetic theory, which describes the motion of a small particle in a liquid. In 1905, Albert Einstein wrote a paper on this motion, explaining it as random collisions between molecules. In the same year, another scientist,…
