A thermodynamic process is shown in the following figure. 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:
`P_(A) = 3 xx 10^(4) Pa, V_(A) = 2xx 10^(-3) m^(3)`
`P_(B) = 8 xx 10^(4) Pa, V_(C) = 5 xx 10^(-3) m^(3)`

Options

A. `560 J`
B. `800 J`
C. `600 J`
D. `640 J`

Answer

A
