This lecture introduces the kinetic theory of gases, focusing on the microscopic description of gas components at thermal equilibrium to derive the ideal gas law. The theory assumes uniform distribution of molecules, isotropic velocities, and independent velocity components. The lecture covers the transfer of momentum from gas molecules to a piston, calculations for molecules hitting the piston per unit time, and the density of particles with specific velocities. It also discusses the concept of isotropic velocities and the probability of having the velocity vector in a given direction, leading to the derivation of the ideal gas law.
