Question
In given figure, let ᐃU1 and ᐃU2 be change in internal energy in process A and B respectively. ᐃQ and W be the net heat given and net work done by the system in the process A + B, then
Options
A.ᐃU1 + ᐃU2 = 0
B.ᐃU1 − ᐃU2 = 0
C.ᐃQ − W = 0
D.ᐃQ + W = 0
Solution
in cyclic process ᐃU1 + ᐃU2 = 0 ᐃUNet = 0 ᐃQ − ᐃW = 0
