The ratio of specific heats of an ideal gas is –

A

11−RCP\frac{1}{1 - \frac{R}{C_{P}}}

B

1+RCV1 + \frac{R}{C_{V}}

C

11−CVR\frac{1}{1 - \frac{C_{V}}{R}}

D

CVCP+R\frac{C_{V}}{C_{P}} + R

Answer

1+RCV1 + \frac{R}{C_{V}}

Explanation

Solution

Q CP – CV = R, CPCV−1\frac{C_{P}}{C_{V}} - 1 = RCV\frac{R}{C_{V}}

\ CPCV\frac{C_{P}}{C_{V}} = g = 1 + RCV\frac{R}{C_{V}}
