Specific heat of a gas for a reversible adiabatic process is
A. Negative
B. Zero
C. Infinity
D. None of these
Answer: Option B
Solution (By Examveda Team)
Since for a reversible adiabatic process the entropy is constant.The heat-capacity and entropy relation is given by
$$\eqalign{ & \frac{{{C_P}}}{T}dT = dS \cr & \Rightarrow {C_P} = 0. \cr} $$
