Chemistry - Thermodynamics - I Question with Solution | TestHub

${\mathrm{C}}_{\mathrm{p}}$is molar heat capacity at constant pressure. Since the quantity is defined at constant pressure, it does not vary with pressure.
At higher temperatures, the rotational degree of freedom becomes active.
$C_P=\frac{7}{2}R\text{ (Independent of }P\text{ ) }$
${\mathrm{C}}_{\mathrm{V}}=\frac{5}{2}\mathrm{R}\text{ (Independent of }\mathrm{V}\text{ ) }$
${\mathrm{C}}_{\mathrm{V}}$ depends on $\mathrm{T}$ and independent on $\mathrm{V}$.
${\mathrm{C}}_{\mathrm{P}}$ depends on $\mathrm{T}$ and independent on $\mathrm{P}$.
