The word ‘thermodynamics’ is composed of two words, namely ‘Thermo’ and ‘dynamics’. ‘Thermo’ stands for heat while ‘dynamics’ is used in connection with mechanical motion which involves ‘work’ done. Thus, thermodynamics is the branch of physics which deals with process involving heat, work and internal energy.
There are two ways of studying the behavior of the system. One is microscopic behavior which deals with the study of atoms and molecules of the substance, constituting that system. Second way is to study the macroscopic behavior. In this way we study the average behavior of extremely large study the average behavior of extremely large number of atoms/molecules constituting the system.
In thermodynamics we deal with quantities like temperature, pressure, volume, internal energy, etc. These quantities, actually, describe the average behaviorof a large number of atoms/molecules or the pressure exerted by a few molecules. Instead we talk about temperature of pressure of a gas which contains a large number of molecules. Thus, thermodynamics is concerned with macroscopic behavior rather than microscopic behavior of the system.
