The specific heat at constant pressure and at constant volume for an ideal gas are `C_(p) and C_(v)`and its adiabatic and isothermal eleasticities are `E_(phi) and E_(theta)` respectively. The ratio of `E_(phi)` to `E_(theta)` is

A

`C_(v)//C_(p)`

B

`C_(p)//C_(v)`

C

`C_(p)//C_(v)`

D

`1//C_(p)C_(v)`

Text Solution

Verified by Experts

The correct Answer is:
B
Ratio of adiabatic and isothermal elasticities
`(E_(phi))/(E_(theta))= (gamma P)/(P) = gamma= (C_(P))/(C_(V))`
