Unformatted text preview: first order phase transi+on. •  These are the transiFons we’re studying There are other types of phase transi+ons: glass, polymers etc. You’ll See This Again (and again) Clausius - Clapeyron Eqn. −ΔH vap Single T : ln Pvap = + ln β RT β depends on the gas Two Ts : (C − CEqn1 ) − (C − CEqn 2 ) ȹ P2 ȹ −ΔH vap ȹ 1 1 ȹ lnȹ ȹ = ȹ − ȹ RT ȹ T2 T1 Ⱥ ȹ P1 Ⱥ Use to calculate a phase boundary.
