Two metal objects, A and B, each of mass 64.5 g, are prepared at 360 K and 280 K,respectively. They are brought into thermal contact and allowed to reach thermalequilibrium while insulated from the rest of the universe (i.e. no heat exchange). Object Ahas a specific heat of cs = 0.285 J/g.K, and object B has a specific heat of cs = 0.210 J/g.K.(a) What is the final temperature (in K) of the system once it reaches thermal equilibrium?(b) What is the entropy change (in J/K) for the system of two objects as they go through theprocess of reaching thermal equilibrium?
