The Figure Shows a P $V$ Diagram for a Gas Going Through a Cycle from a Going

question 8

Short Answer

The figure shows a p $V$ 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 heat 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 by the gas from A to B?
(b) How much heat was absorbed by the gas from B to C?
(c) How much work was done by the gas going from B to C?
