Specific heat of a gas undergoing adiabatic change is

Specific heat of a gas undergoing adiabatic change is
  1. zero
  2. infinite
  3. positive
  4. negative

Solution

As we know that, In case of adiabatic condition, heat change, $\Delta Q=0$ and $\Delta Q=n C_V \Delta T$ where, $n$ is number of moles and $\Delta T$ is change in temperature. $ \therefore \quad C_V=\frac{\Delta Q}{n \Delta T}=0 $
