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

A

`7/5`

B

`8/7`

C

`5/7`

D

`9/7`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(p)=(7)/(2)RimpliesC_(V)=C_(P)-R=(5)/(2)Rimpliesgamma=(C_(P))/(C_(V))=(7)/(5)`
