Question:medium

The specific heat capacity of a gas at constant pressure ($C_p$) and at constant volume ($C_v$) are related as

Show Hint

Remember that for an ideal gas, the difference between the specific heat capacities at constant pressure and constant volume is always equal to the universal gas constant $R$.

Updated On: May 31, 2026

$C_p - C_v = R$
$C_v - C_p = R$
$C_p / C_v = R$
$C_p + C_v = R$
