An ideal monatomic gas begins in an initial state, i, at P and V. It then undergoes a process with a final state at 3.5 P and V as shown. What is the heat added to the gas in the process in terms of PV, i.e., what is the value of x in Q = xPV? . Hint: Recall pV = nRT, or T = pV nR Pressure f 3P 2P P 0 0 V 22 2V 3V Volume 4V
