Thermodynamics and Statistical Mechanics (PHY-202):

The course of “Thermodynamics and Statistical Mechanics” is introducing fundamental aspects of heat flow behavior.  Statistical mechanics deals with average effects of large number of individuals.Thermodynamics literally means heat in motion. It is that branch of physics which deals with transformation of heat energy in to mechanical energy and vice versa. It is widely used in the design of heat engine, steam turbines, refrigerator, physical chemistry and chemical physics. To get a deeper inside and understanding in to the laws of thermodynamics, the molecular concept of matter can be incorporated into the study of thermodynamics by means of statistical mechanics.
