If $n$ denotes the number of degrees of freedom of the molecule of an ideal gas:

Options:(select one or more)

Answer:

A, B, D

Solution:

$C_{V} = \frac{n R}{2}$ (A true); $C_{P} = \frac{n R}{2} + R$ (C false). A molecule needs at least 3 translational degrees of freedom, so $n \geq 3$ (B true).

$γ = \frac{C _{P}}{C _{V}} = 1 + \frac{2}{n} (D true).$
