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.
Waves: A disturbance that travels by a medium is called wave.
