You are asked to estimate the boiling point of a liquid.
You are given a plot of vapor pressure versus temperature for the liquid.
The boiling point is the temperature at which the vapor pressure is equal to the external pressure. From the graph in Interactive Figure 11.2.4, the vapor pressure of heptane is approximately 595 mm Hg at 90 °C.
