Laws Of Thermodynamics
Thermodynamics laws define the fundamental physical quantities like energy, temperature and entropy that characterize thermodynamic systems at thermal equilibrium. These thermodynamics laws represent how these quantities behave under various circumstances.
There are four laws of thermodynamics and are given below:
First law of thermodynamics: Energy can neither be created nor be destroyed, it can only be transferred from one form to another.
Second law of thermodynamics: The entropy of any isolated system always increases.
Third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches absolute zero.
Zeroth law of thermodynamics: If two thermodynamic systems are in thermal equilibrium with a third system separately, then they are in thermal equilibrium with each other.
