First Law of Thermodynamics: 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 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?
