1.	A thermodynamic process is as shown in figure such that P_(A) = 3 xx 10^(4)Pa, P_(B) = 8 xx 10^(4) Pa, V_(A) = 2 xx 10^(-3) m^(3), V_(D) = 5 xx 10^(-3) m^(3) In procss AB, 600 J of heat is added to the system and in process BC, 200 J of heat is added to the system. The change in internal energy of the system in proess AC is
