Question:

Two large heat reservoirs at temperatures 200 oC and 60 oC, respectively, are brought into thermal contact, and 1.50 x 103J of heat spontaneously flows from one to the other with no significant temperature change.
(a) The change in the entropy of the two-reservoir system is (1) positive, (2) zero, (3) negative. Explain.
(b) Calculate the change in the entropy of the two-reservoir system.
