Lecture
This lecture covers the kinetic theory of gases, focusing on the behavior of gas molecules, the microscopic interpretation of gas pressure, and the models of real and ideal gases. It explains the calculation of pressure in a perfect gas by applying the momentum theorem to gas particles in a confined space. The lecture also discusses the equipartition of energy, the distribution of velocities, and the internal energy of a perfect gas. Key concepts include the Van der Waals model, the Boltzmann and Maxwell distribution functions, and the principle of equipartition for gases, liquids, and solids.
