Question

. Indicate whether each statement is true or false. If it is false, rephrase the statement so that it is true. 1. The entropy of the universe increases for any spontaneous process. 2. The entropy change of the system is equal and opposite that of the surroundings for any irreversible process. 3. The entropy of the system must increase in any spontaneous process. 4. The entropy change for an isothermal process depends on both the absolute temperature and the amount of heat reversibly transferred. 5. The third law of thermodynamics says that the entropy of a perfect, pure crystal at absolute zero increases with the mass of the crystal

Explanation / Answer

True/False statement

1. The entropy of the universe increases for any spontaneous process. : True

2. The entropy change of the system is equal and opposite that of the surroundings for any irreversible process. : False

Entropy of reversible system have same entropy for system and surrounding only the sign differs.

3. The entropy of the system must increase in any spontaneous process. : True

4. The entropy change for an isothermal process depends on both the absolute temperature and the amount of heat reversibly transferred. : True

5. The third law of thermodynamics says that the entropy of a perfect, pure crystal at absolute zero increases with the mass of the crystal. : True
