Suppose that the specific heat capacity cp Of the body discussed in Section 7.6 of the text is 10 J kg-1 K-1and T1 =200 K. Assume that the mass of the body is 1 kg.
a) Calculate the change in entropy of the body and of the reservoir if T2= 400 K
b) Make the same calculation for T2=100 K.
c) Find the entropy change of the universe in both cases.
