As shown in the PV diagram below, the cycle goes in the order of states A-B-C-D, and the system is one mole of a monatomic gas. The processes between each state are labelled as 1 through 4. For which process or processes will the entropy change be greater than or equal to zero (A.S > 0)? 1 A 4Po 3Po 4 2Po Po D 3 Vo 2Vo 3Vo 4Vo O All processes O Process 1 only O Processes 1 and 4 O Processes 2 and 3 O Processes 2 and 4
