The PV diagram in the figure below shows a set of thermodynamic processes that make up a cycle ABCDA for a monatomic gas, where AB is an isothermal expansion occurring at a temperature of 370 K. There are 1.95 mol of gas undergoing the cycle with $P_A = 1.01 \times 10^6$ Pa, $P_B = 5.10 \times 10^5$ Pa, and $P_C = 2.02 \times 10^5$ Pa. (a) Find the volumes $V_A$ and $V_B$ $V_A = $ $V_B = $ m$^3$ (b) Find the work done in each process of the cycle and the total work done for the whole cycle. $W_{AB} = $ $W_{BC} = $ $W_{CD} = $ $W_{DA} = $ $W_{tot} = $ (c) Find the change in thermal energy during the constant-volume process BC.
