25 min Phase Diagrams — Thermodynamic Stability & Phase Transitions

The Clausius-Clapeyron tool computes vapour pressure at any temperature given a reference point and the molar enthalpy of vaporisation. The canvas plots ln(p) vs 1/T — a straight line whose slope is −ΔvapH/R. The deviation from linearity at high T (not captured here) reflects the temperature dependence of ΔvapH.
