Question
A fixed mass of gas undergoes changes of pressure and volume as shown below. When the gas is taken from state P to state R by stages PQ and QR, 8 kJ of heat are absorbed by it and 3 kJ of work are done by it. When the same resultant change is achieved by stages PS and SR, 1 kJ of work is done by the gas. In this case which of the following represents the heat transfer? Select one: O a. 8 kJ of heat are absorbed O b. 4 kJ of heat are rejected Oc. 12 kJ of heat are rejected O d. 10 kJ of heat are absorbed e. 6 kJ of heat are absorbed
