5 moles of oxygen are heated at constant volume from `10^(@)C` to `20^(@)C`. The change in internal energy of a gas.
`[C_(P)=7.03 cal mol^(-1) deg^(-1)` and `R=8.3J mol^(-1) deg^(-1)]`

A

125 cal

B

252 cal

C

50 cal

D

500 cal

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(P)-C_(V)=R, q=n C_(V)Delta T`
since `W=0" "DeltaU=q+W, Delta U=q`
