Kinetic Theory of Gases
The Kinetic Theory of Gases serves as a foundational framework in understanding the behavior of gases at the molecular level. Developed in the 19th century, this theory elucidates how gas molecules move, interact, and exert pressure within a container. At its core, it posits that gas particles are in constant motion, colliding with each other and the walls of their container, thereby explaining macroscopic properties like temperature and pressure. By considering the motion and energy of individual molecules, the Kinetic Theory provides valuable insights into phenomena such as diffusion, thermal conductivity, and ideal gas behavior.
