Question

Quizplus · Accepted Answer

The substance with the highest boiling point (in this case, water with a boiling point of 100°C) will have the lowest vapor pressure at room temperature. This is because vapor pressure is inversely proportional to boiling point, meaning that substances with higher boiling points will have lower vapor pressure.
