Vedclass · Answer

(D) According to Mayer's relation,for any ideal gas,the difference between the molar specific heat at constant pressure $(C_P)$ and the molar specific heat at constant volume $(C_V)$ is equal to the universal gas constant $(R)$.$C_P - C_V = R$.The value of the universal gas constant $R$ is approximately $1.987 \, 	ext{cal/mol-K}$,which is often rounded to $1.99 \, 	ext{cal/mol-K}$.Therefore,for hydrogen gas $(H_2)$,which behaves as an ideal gas under standard conditions,$C_P - C_V = 1.99 \, 	ext{cal/mol-K}$ is the correct statement.

Which of the following statements is correct regarding the molar specific heat of $1$ mole of an ideal gas at constant pressure $(C_P)$ and constant volume $(C_V)$?
