Expert Answer:

Thermodynamics is a branch of science which deals with the exchange of heat energy between bodies and conversion of the heat energy into mechanical energy and vice versa.
Thermodynamics refers to a macroscopic description of bodies and processes.It is considered as a macroscopic science because the state of a gas in thermodynamics is specified by macroscopic variables like pressure, volume, temperature, mass, composition etc. Thermodynamics does not describe the microscopic behaviors of the large number of its microscopic constituents(molecules), whereas it describes the bulk behavior of the body .In thermodynamics we are not concerned about the motion of the system as a whole.We study the changes in the internal macroscopic state.Such studies are carried out in terms of the macroscopic properties such as pressure,volume,temperature etc.
