Plots the saturation pressure versus temperature predicted by the Clausius-Clapeyron equation for five molecules. Also plotted is the Antoine equation, which is obtained by a fit to experimental data. For water, click "add experimental data" to display data points. The plots of vapor pressure versus temperature are shown over a narrow temperature range near the boiling point at 1-atm pressure (click "near boiling point") or over a range from the triple point to the critical point (click "extended range"). When log scale is selected, the log of the saturation pressure is plotted versus the inverse temperature. The heat of vaporization at the boiling point at 1-atm pressure was used for the Clausius-Clapeyron equation.
