Which of the following factor does not affect the magnitude of vapor pressure?
Correct answer: A. amount of liquid
- A. amount of liquid
- B. size of molecule
- C. temperature of liquid
- D. intermolecular forces
Explanation
The amount of liquid does not affect the magnitude of vapor pressure. Vapor pressure is primarily determined by the temperature of the liquid, the intermolecular forces between the molecules in the liquid, on the size of the molecules.

About Evaporation, Boiling Point and Vapour Pressure
Evaporation is the escape of higher-energy molecules from a liquid surface, while vapour pressure is the pressure exerted by vapour in equilibrium with that liquid. The topic distinguishes evaporation from boiling and relates both to temperature, intermolecular forces, surface area, atmospheric pressure and the boiling point.
