Thermodynamic laws

Thermodynamics:
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.
