If the degree of freedom of a gas are f, then the ratio of two specific heats CP/CVC_{P}/C_{V} is given by

A

2f+1\frac{2}{f} + 1

B

1−2f1 - \frac{2}{f}

C

1+1f1 + \frac{1}{f}

D

1−1f1 - \frac{1}{f}

Answer

2f+1\frac{2}{f} + 1

Explanation

Solution

CPCV=γ=1+2f\frac{C_{P}}{C_{V}} = \gamma = 1 + \frac{2}{f}
