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 ${H_2}$

    $Assertion :$ The ratio of $\frac{C_p}{C_v}$ for an ideal diatomic gas is less than that for an ideal monoatomic gas (where $C_p$ and $C_v$ have usual meaning).
    $Reason :$ The atoms of a monoatomic gas have less degrees of freedom as compared to molecules of the diatomic gas.
