Irreversible work
WebIrreversible isothermal compression The irreversible compression of the gas proceeds in one step against a constant external pressure of 3.0atm. w = -PextΔV = 0.060 Latm The work done on the gas is positive because the gas is compressed; the surroundings do positive work onthe gas. How do we compute the heat added to the gas? Indirectly!
