Q. For the specific heat of 1 mole of an ideal gas at constant pressure $(C_{P})$ and at constant volume $(C_{V})$ which is correct
A) $C_{P}$ of hydrogen gas is $\frac{5}{2}R$
B) $C_{V}$ of hydrogen gas is $\frac{7}{2}R$
C) $H_{2}$ has very small values of $C_{P}$ and $C_{V}$
D) $C_{P} - C_{V} = 1.99\ cal/mole - K$ for $H_{2}$
Explanation
(d) For any gas $C_{P} - C_{V} = 1.99 = 2\frac{cal}{mol - K}$
