The figure shows a pV diagram for a gas going through a cycle from A to B to C and back to A.From point A to point B,the gas absorbs 50 J of energy through heating and finds its internal (thermal)energy has increased by 20 J.Going from B to C,the internal (thermal)energy decreases by 5.0 J.
(a)How much work was done in the gas from A to B?
(b)How much energy through heating was absorbed by the gas from B to C?
(c)How much work was done on the gas going from B to C?
