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 Heat supplied to the system during the change of state from A to B.
Answer» SOLUTION :For the change of STATE from A to B, ` DELTA Q =Delta U +Delta W =(U_B -U_A ) +Delta W = (50 - 10)J +(+80J) = 40 J` Thus, heat supplied to the system is 40 J.
