thermodynamics is the branch of physics which deals with the study of transformation of heat energy into other form and vice versa One of the most important concept of thermodynamics is the temperature for example We are cautious about hot foods hot stoves. Agricultural engineers are concerned with weather conditions for the health of crops Doctors are concerned about their present temperature for further investigation food engineers are concerned with proper heating and proper cooling of item of food. Geologist are concerned with the transfer of thermal energy and so on. an assembly of an extremely large number of particles of atom or molecules is called thermodynamics system.such a system may exist in the form of a solid liquid or gas or a combination of two or more States. thermodynamics system is said to be in thermodynamic equilibrium when macroscopic variables like pressure volume temperature mass composition etc that characterize the system do not c...
