Introduction to Thermodynamics

Thermodynamics : It is a branch of science which deals with the exchange of energy in the form of heat or work between system and surroundings. It deals with the conversion of the heat energy into mechanical energy and vice-versa.

Thermodynamic system and surroundings : The collection of an extremely large number of atoms or molecules which are confined within certain boundaries (either fixed or moveable) such that it has a certain value of pressure, volume and temperature is called a thermodynamic system.

Anything outside the thermodynamic system to which energy or matter is exchanged is called its surroundings.

Example : Suppose there is Piston-cylinder arrangement which contains any gas within it, then the gas enclosed in a cylinder fitted with a piston forms the thermodynamic system but the atmospheric air which is outside the cylinder, movable piston are surroundings.

 

Thermodynamic system are classified in three major categories - 

(i) Open system : It exchange both energy and matter with the surroundings.

(ii) Closed system : It exchange only energy (not matter) with the surroundings.

(iii) Isolated system : It exchange neither energy nor matter with the surroundings.
