A sample of an ideal gas is taken through the cyclic process abca shown in Fig.21-33. The scale of the vertical axis is set by p_b = 7.5 kPa and p_(Ac ) = 2.5 kPa. At point a, T = 280 K. (a) How many moles of gas are in the sample? What are (b) the temperature of the gas at point b, (c) the temperature of the gas at point c, and (d) the Higure 21-33 Problem 30. net work done by the gas during the cycle, and (c) the net energy added to the gas as heat during the cycle?
