Entropy: Two identical bodies with heat capacities at constant volume which vary linearly with tempereature Cv=10T, are thermally isolated from the environment. One is at a temperature of 100K, the outer is at 200K. They are placed in thermal contact and come to thermal equilibrium. (Assume that there is no volume change.)
(a.) What is the final temperature of the two bodies?
(b.) What is the entropy change of the system?
(c.) What is the entropy change of the universe?
