Question

A thermodynamic process is shown in the following figure. The pressure and volumes corresponding to some points in the figure are PA = 3 × 104 Pa, PB = 8 × 104 Pa, VA = 2 × 10–3 m3, VD = 5 × 10–3 m3. In the process AB, 600 J of heat is added to the system and in BC, 200 J of heat is added to the system. The change in internal energy of the system in the process AC would be

Options

A.560 J
B.800 J
C.600 J
