600J of heat is added to a monoatomic gas in a process in which the gas performs a work of 150J. The molar heat capacity for the process is

A

3R

B

4R

C

2R

D

6R

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaU=Q-W=450J=nC_VDeltaT`
`=n(3/2R)DeltaT`
`:.` `nDeltaT=(300/R)`
Now, `C=(Q)/(nDeltaT)`
`=(600)/(300//R)=2R`
