A sample of mono-atomic ideal gas is taken through a cyclic process ABCDA. A graph is plotted in which heat exchanged by the gas upto an instant is shown on x-axis and work done by the gas upto that instant is shown on y-axis.
Choose incorrect statement:
A. Magnitude of temperature change in the process AB and CD are same
B. Process AB and CD are isochoric
C. Process BC and DA are isothermal
D. Molar heat capacity in process AB is `(5)/(2)` R.
