`294` joules of heat is requied to rise the temperature of `2` mole of an ideal gas at constant pressure from `30^(@)C` to `35^(@)C` . The amount of heat required to rise the temperature of the same gas through the same range of temperature at constant volume `(R=8.3 "Joules/mole"-K)` is

A

`12.6J`

B

`211J`

C

`29.4K`

D

`37.8J`

Text Solution

Verified by Experts

The correct Answer is:
B
`(DeltaQ)_(P)=nC_(P)DeltaT` :
`C_(P)-C_(V)=RimpliesC_(V)=C_(P)-R,(DeltaQ)_(V)=nC_(V)DeltaT`
