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 ΔSh in the entropy of the hot object, the change ΔSc in the entropy of the cold object, and the change ΔStotal in the entropy of the combination are:
a) ΔSh > 0, ΔSc > 0, ΔStotal > 0
b) ΔSh < 0, ΔSc > 0, ΔStotal > 0
c) ΔSh < 0, ΔSc > 0, ΔStotal < 0
d) ΔSh > 0, ΔSc < 0, ΔStotal > 0
e) ΔSh > 0, ΔSc < 0, ΔStotal < 0
