One mole of a gas absorbs 200 J of heat ...

One mole of a gas absorbs 200 J of heat at constant volume. Its temperature rises from 298 K to 308 K. The change in internal energy is :-

A

200 J

B

`-200 J`

C

`200xx(308)/(298)`

D

`200xx(298)/(308)J`

Text Solution

Verified by Experts

The correct Answer is:
A
At constant volume `-Delta V = 0`
so `W = -P.Delta V = 0`
according to `FLOT rArr Delta E = q = 200 J`
