Definition - What does Kinetic Theory mean?
Kinetic Theory is a theory that states the thermodynamic behavior of gases. According to a study which was carried out, minute particles of gases move at a random motions hence they undergo elastic collisions. It also explains the main five postulates that describe the performance of gas molecules in terms of physical properties like momentum, mass and energy. It is useful when you need to know the gas molecular speed, distance between molecules and effusion rates.
Petropedia explains Kinetic Theory
The ideal gas law was used to discuss the relationship between the gas molecules. However, in the 18th century the Kinetic Theory of gases was introduced by Maxwell. According to the theory, it correlates the microscopic phenomena with the macroscopic properties of gas molecules. It also helps in calculating the pressure on the vessel walls by random collisions of molecules that depend on gas temperature. Furthermore, kinetic energy is directly proportional to the outright temperature of gases. The Kinetic Theory is best suited to real gases than ideal gases.
