Question

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases. please Explain this to me in 2-3 paragraphs.

Answer 1

First law tells that heat given to a system will be used to increase in internal energy plus to do some external work,

this states that heat energy is converted in to other forms but no energy created aswell as destroyed.

According to second law of thermodyanamics heat cannot go itself from cold body to hot body ,

it also states that any process that takes place from one state to another state will always takes in a manner that

entropy increases,if we go against this heat should go itself from cold body to hot body which is impossible
