ENGR5003 Lecture 2, slide 17 (p-V and T-s diagrams)

On a P-V diagram, what does the area under a process curve represent?

Formulas you may need

Boundary work: $W = \int p\,dV$ (area under the p-V curve) (on the formula sheet)
Reversible heat: $Q = \int T\,dS$ (area under the T-s curve) (on the formula sheet)
