Consider an ideal gas that undergoes two alternative processes from state 1 to state 2. The path for the fi rst process (Path 1) is reversible, and the path of the second process (Path 2) is irreversible.
Answer the following questions.

(a) If we compare the entropy change of the system, we can say that the entropy change for Path 1 is (greater than, equal to, less than) the entropy change for Path 2. Explain.

(b) If we compare the entropy change of the surroundings, we can say that the entropy change for Path 1 is (greater than, equal to, less than) the entropy change for Path 2. Explain.
