1.

A gas is compressed at a constant pressure of `50N//m^(2)` from a volume `10m^(3)` to a volume of `4m^(3)`. 100J of heat is added to the gas then its internal energy isA. Increased by 400 JB. Increased by 200 JC. Increased by 100 JD. Decreased by 200 J

Answer» Correct Answer - A
From FLOT `DeltaU=DeltaU+DeltaW=DeltaU+PDeltaV`
`rArr 100=DeltaU+ 50 xx (4 -10) rArr DeltaU=400 J`
