Question

What are the limitations of 1st law of thermodynamics? State Second law of thermodynamics associated with the refrigerator​

Answer 1

Answer:

your first answer

The limitation of the first law of thermodynamics is that it does not say anything about the direction of flow of heat. It does not say anything whether the process is a spontaneous process or not. The reverse process is not possible. In actual practice, the heat doesn't convert completely into work.

Explanation:

The Clausius statement of the Second Law of Thermodynamics forbids heat to flow from cold to hot unless external work is done. ... Therefore the net effect of the refrigerator is to make the cold reservoir colder by removing heat from it and moving that heat to the hot reservoir
