Thermodynamic laws:

First law of thermodynamics

In internal energy of a system the change is the total heat transferred to or from the system & the work done on or by the system.

Second law of thermodynamics

The entropy is a measure of the unavailability of a system's energy to do useful work of a closed system tends to enhance with time.

Third law of thermodynamics

For changes including only perfect crystalline solids at absolute zero, the change in the over all entropy is zero.
