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

A

`-2660.23J`

B

`-2777.23 J`

C

`-2767.23 J`

D

`-2600 J`

Text Solution

Verified by Experts

The correct Answer is:
C
Change in internal energy `DeltaU=nC_vDeltaT, n ` No of moles `C_v=R/(gamma-1):.DeltaU=(nR)/(gamma-1)DeltaT`
`DeltaU=(2xx8.31xx(189-300))/(5/3-1)=-2767.23J`
