Specific Heats of Gases - Cp, Cv, γ & Mayer's Relation

The molar specific heat at constant pressure of an ideal gas is (7/2) R. The ratio of specific heat at constant pressure to that at constant volume is

Show answer and solution

Answer: (b)

$C_v = C_p - R = \frac{7}{2}R - R = \frac{5}{2}R$ .
$\gamma = \frac{7/2}{5/2} = \frac{7}{5}$
So the answer is (b) 7/5.
