The type of ideal gas that will have the largest value of CP is a monatomic gas.
In thermodynamics, CP refers to the molar heat capacity at constant pressure. For a monatomic gas, the heat capacity at constant pressure (CP) is given by:
CP = (5/2)R
Where R is the gas constant. The factor of (5/2) arises from the fact that a monatomic gas has three degrees of freedom for translation, and two degrees of freedom for rotation (since it does not have any rotational energy associated with vibration). Therefore, a monatomic gas has a higher CP value compared to diatomic or polyatomic gases, which have additional degrees of freedom associated with molecular vibrations.
Thus, a monatomic gas will have the largest value of CP among ideal gases.
