Vedclass · Answer

(D) Helium is a monoatomic gas. For an ideal gas,the relationship between molar specific heat at constant pressure $(C_p)$ and molar specific heat at constant volume $(C_V)$ is given by Mayer's relation: $C_p - C_V = R$. Given: $C_V = 12.6 \ J \ mol^{-1} \ K^{-1}$ and $R = 8.314 \ J \ mol^{-1} \ K^{-1}$. Substituting these values into the equation: $C_p = C_V + R$. $C_p = 12.6 + 8.314 = 20.914 \ J \ mol^{-1} \ K^{-1}$. Rounding this value to the nearest integer,we get $C_p \approx 21 \ J \ mol^{-1} \ K^{-1}$.

The specific heat of helium at constant volume is $12.6 \ J \ mol^{-1} \ K^{-1}$. The specific heat of helium at constant pressure in $J \ mol^{-1} \ K^{-1}$ is about (Assume the temperature of the gas is moderate,universal gas constant,$R=8.314 \ J \ mol^{-1} \ K^{-1}$)
