1.	Figure depicts the working diagram (P-V graph) of a process corresponding to an ideal gas. Suppose U_A=10J, U_B = 50 J and heat given to the gas during the process BC is 40 J. Determine Work done during the entrie process ABCA.
Answer» Solution :Work done during the PROCESS ABCA `= W_(AB) + W_(BC)+W_(CA)= (6-2)m^3xx 20 Nm^(-2) - 1401 + 0 `[from (a) and (b)] = -60J
