The aim of the lecture is to explain macroscopic properties of matter (mostly gases), such as pressure, temperature, viscosity, thermal conductivity and others by considering their molecular composition. Emphasis is placed on a statistical approach to the problem. The main attention is devoted to the basis of classical kinetic theory of gases. The lecture deals not only with gases in thermodynamic equilibrium, but also with gases not in thermodynamic equilibrium. This means considering what are known as transport properties, such as viscosity and thermal conductivity.
