One mole of an ideal diatomic gas undergoes a process AB as shown. Pressure at A and B are  5 P0 and P0 while volumes are V0 and 5V0 respectively. On the basis of the given information answer the following question (s).Choose the correct option regarding the process A→B.During the process from  A→B, pressure and volume of the gas, where the direction of flow of heat is reversed, is

Temperature of gas at A and B is equal so  ΔU=0.Equation of processP=−P0V0V+6P0     ... (1)Heat reverse its direction when slope of line should be equal to γPV=P0V0 .. (2)From equation (1) and (2)V=72V0,  P=52P0Temperature of gas at A and B is equal so  ΔU=0.Equation of processP=−P0V0V+6P0     ...
