Question

The molar heat capacity for the process shown in the figure is
(a) C = Cp
(b) C = Cv
(c) C > Cv
(d) C = 0.
Figure

Answer 1

Option (d) is correct

Explanation:

The process described here is

$p=\frac{k}{V g}$

$p V g=k$

So, the process is adiabatic where there is zero heat supplied to the device, i.e. Q = 0 Q = 0.

Molar heat capacity is stated as the amount of heat which is supplied to the system per mole to induce temperature change in degree.

No heat exchange is permitted in an adiabatic process, too. So, the heat capacity of molars is equal to zero, i.e. C = zero.
