why is entropy increases in universe?what is entropy?
Entropy is constant only in reversible processes which occur in equilibrium. ... Butentropy can only remain constant in a reversible isothermal process. So, again, any heat transfer would have to occur isothermally.ENTROPY is the measure of degree of randomness and disorderness of the gas molecules , HOPE IT CLEARS YOUR DOUBT ALL THE BEST ..
ENTROPYThe measuring of the disorder of the system is called EntropyEntropy of system increases during an irrevrsible heat transfer.Since the system is isolated from surroundings,there will be no change in entropy of surroundings duringthis process.Hence entropy of univers will increase by irrversible heat trnsfer or conduction of heat
