A brass rod is in thermal contact with a constant temperature reservoir at 130oC at one end

Question:

A brass rod is in thermal contact with a constant temperature reservoir at 130oC at one end and a constant temperature reservoir at 24.0oC at the other end.

(a) Compute the total change in entropy of the rod-reservoirs system when 5030 J of energy is conducted through the rod, from one reservoir to the other.

(b) Does the entropy of the rod change?
