Question

state first and third law of thermodynamic...and write expression mathematically..?​

Answer 1

Answer:

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.

Answer 2

Explanation:

states that energy cannot be created or destroyed in an isolated system. The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
