The temperature of `5 mol` of gas which was held at constant volume was change from `100^(@)C` to `120^(@)C`. The change in internal energy was found to ve `80 J`. The total heat capacity of the gas at constant volume will be equal to

A

8J/K

B

4.0 J/K

C

0.8 J/K

D

0.4 J/K

Text Solution

Verified by Experts

The correct Answer is:
B

`du=nC_(V)dT`
`therefore C_(V)=(du)/(ndT)=(80)/(5xx20)`
`C_(V)=0.8J//K`.
