A system absorbs 200 J of heat reversibly from a reservoir at 300 K and gives off

Question:

A system absorbs 200 J of heat reversibly from a reservoir at 300 K and gives off 100 J reversibly to a reservoir at 200 K as it moves from state A to state B. During this process, the system does 50 J of work.

(a) What is the change in the internal energy of the system?

(b) What is the change in entropy of the system?

(d) If the system goes from state A to state B by a nonreversible process, how would your answers for parts (a), (b), and (c) differ?
