It is deals with relation between work, heat and other form or energy.
It gives many relationships between properties of matter and efficiencies of various processes.
First law of thermodynamics:-
First law of thermodynamics concern with conservation of energy.
According to law energy can neither be created or nor be destroyed. It can transform only one form to another form .
The total sum of all energy in the universe remain constant.
Thermodynamics second law :--
According to kelvin - plank statement no cyclic process is possible whose result is the flow of heat from a single heat reservoir and the performance of an equivalent amount of work on a work reservoir.
According to second law , In a cyclic device heat abstract continuously from a single reservoir , is totally convert to mechanical work is impossible.
