Problem 4: An ideal diatomic gas in a cylinder near room temperature undergoes the cyclic process shown. The four steps in the process are labeled A, B, C, and D. 1 (b) P2 V2 Volume Vị For each of the steps, A, B, C, D, determine whether each of the following is positive, negative, or zero: The work done on the gas. The change in energy content of the gas. The heat added to the gas. Express answers in terms of P1, P2, V1, and V2, then determine the sign. a) Make the table below showing, for each of the four steps, the sign (+, -, or 0) of W, Q and AU. AU B D b) Compute the net heat added, the net work done, and the net change in internal energy for one complete cycle.
