In the above question, change in internal energy of gas is

A

`-2660.23J`

B

`-2777.23J`

C

`-2767.23J`

D

`-2600J`

Text Solution

Verified by Experts

The correct Answer is:
C
Change in internal energy `DeltaU=n C_(v) DeltaT`
Where `n` is the number of moles.
As `C_(v)=R/(gamma-1)`
`:. DeltaU= (nR)/(gamma-1) DeltaT`
`DeltaU= (2xx8.31xx(189-300))/(5/3-1)= -2767.23J`
