Figure (Five straight line numbered 1, 2, 3, 4 and 5) shows graph of change in temperature `Delta T` verusus heat supplied `Delta Q` for different process performed on a gas of one mole.
A. lines 4 and 5 (coinciding with `Delta Q` and `Delta T` axis respectively) represent isothermal and adiabatic processes respectively
B. line 2 respesents isochoric process for diatomic gas
C. lines 1 and 3 represent isochoric process for a diatomic gas and isochoric process for a monoatomic gas respectively
D. line 2 represents isobaric process for a monoatomic gas.
