1.	In the given figure, an ideal gas changes its state from state A to state C by two paths ABC and AC. The internal energy of gas at state B is 20 J. Find the amount of heat supplied to the gas to go from A to B
Answer» Solution :As WORK done `W= int PdV`= area under P-V curve, so For PATH AB, first LAW of thermodynamics yields `dQ=(U_b-U_A)+ 0 = 20-10 = 10J`.
