When 1 mol of gas is heated at constant ...

When 1 mol of gas is heated at constant volume temperature is raised from 298 to 308 K. Heat supplied to the gas is 500 J. Then which statement is correct ?

A

`q=W=500J, DeltaU=0`

B

`q= DeltaU=500J,W =0`

C

`q=W = 500 J ,DeltaU=W=0`

D

`DeltaU=0,q=W= - 500J`

Text Solution

Verified by Experts

The correct Answer is:
B
At constant volume, `DeltaV=0`. Hence, `W=0` .Further `DeltaU = q+W`
As `W=0, DeltaU = q= 500J`
