Question

A container has one mole of monoatomic ideal gas. Each molecule has /degrees of freedom. What is the ratio of γ = \(\frac{C_P}{C_V}\)= ?

(a) f

(b) \(\frac{f}{2}\)

(c) \(\frac{f}{f+2}\)

(d) \(\frac{f+2}{f}\)

Answer 1

Correct answer is (d) \(\frac{f+2}{f}\) 

Energy associated with 1 mole of gas, U = \(\frac{f}{2}\) RT
