n moles of an ideal gas with constant volume heat capacity `C_V` undergo an isobaric expansion by certain volume.The ratio of the work done in the process, to the heat supplied is :

A

`(4nR)/(C_V - nR)`

B

`(nR)/(C_V - nR)`

C

`(nR)/(C_V + nR)`

D

(4nR)/(C_V + nR)`

Text Solution

Verified by Experts

The correct Answer is:
C
`(W)/(Q)= (nRtriangleT)/(n_(C_p))(triangleT)= (nRtriangleT)/(n(C_1+R)triangleT)= (R )/(C_v+R)" "C_v` : molar spcific heat of gas
`(R )/((C_v)/(n)+R)= (nR)/(C_v+nR), " "C_v` : specific heat of 'n' moles of gas.
