Unformatted text preview: • This has a variety of names: – expansion work – PdV work – boundary work – compression work 9 Some Common P(V) Paths • P=C , constant pressure process • P=C/V, ideal gas, const.temp. process • PV n =C, polytropic process 10 Polytropic process ∫ = V V PdV W 2 1 A frequently encountered process for gases is the polytropic process: constant c PV n = = Since this expression relates P & V, we can calculate the work for this path....
