n mole a perfect gas undergoes a cyclic process ABCA (see figure) consisting of the following processes. A to B : Isothermal expansion at temperature T so that the volume is doubled from V_1 to V_2 = 2V_1 and pressure changes from P_1 to P_2 B to C : Isobaric compression at pressure P_2 to initial volume V_1 C to A : Isochoric change leading to change of pressure from P_2 to P_1 . Total work done in the complete cycle ABCA is :

One mole of a monatomic ideal gas has an initial pressure, volume, and temperature of P_0 , V_0 , and 438 K, respectively. It undergoes an isothermal expansion that triples the volume of the gas. Then, the gas undergoes an isobaric compression back to its original volume. Finally, the gas undergoes an isochoric increase in pressure, so that the final pressure, volume, and temperature are p_0 V_0 and 438 K, respectively. Find the total heat for this three-step process, and state whether it is absorbed by or given off by the gas.
