question 41

Multiple Choice

A hot object and a cold object are placed in thermal contact and the combination is isolated.They transfer energy until they reach a common temperature.The change $\Delta$ S_h in the entropy of the hot object, the change $\Delta$ S_c in the entropy of the cold object, and the change $\Delta$ S_total in the entropy of the combination are:

• A)"\(\Delta\)S_h > 0, \(\Delta\)S_c > 0, \(\Delta\)S_total > 0"
• B)"\(\Delta\)S_h < 0, \(\Delta\)S_c > 0, \(\Delta\)S_total > 0"
• C)"\(\Delta\)S_h < 0, \(\Delta\)S_c > 0, \(\Delta\)S_total < 0"
• D)"\(\Delta\)S_h > 0, \(\Delta\)S_c < 0, \(\Delta\)S_total > 0"
• E)"\(\Delta\)S_h > 0, \(\Delta\)S_c < 0, \(\Delta\)S_total < 0"
