Question

How is second law of thermodynamics different from the first law of thermodynamics?

Answer 1

The first law of thermodynamics states:
The energy of the universe is constant.
The second law of thermodynamics states:
In any spontaneous process there is always an increase in the entropy of the universe.

Answer 2

1st law states that energy can neither be created nor destroyed i.e. energy of the universe remains constsnt
2nd law states that in all energy exchanges if no energy enters or leaves the system, the potential energy will always be less then that of the initial state..which is commonly referred to as entropy
