Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.

Use the observation in the first column to answer the question in the second column. observation question At any temperature where both substances are liquid, which has the higher vapor pressure? O Substance E The enthalpy of vaporization of Substance E is smaller Substance F than that of Substance F. Neither, E and F have the same vapor pressure. It's impossible to know without more information. Which has a higher boiling point? At 71 °C, substance A has a Substance A vapor pressure of 108. torr and Substance B has a vapor Substance B pressure of 158. torr. Neither, A and B have the same boiling point. It's impossible to know without more information. Which has a higher enthalpy of vaporization? At 1 atm pressure, Substance C Substance C boils at 138. °C and Substance D Substance D boils at 171. °C. Neither, C and D have the same enthalpy of vaporization. It's impossible to know without more information.
