Upon which factor is vapor pressure not dependent:
Correct answer: D. Surface area of liquid
- A. Temperature
- B. Intermolecular forces
- C. Density of liquid
- D. Surface area of liquid
Explanation
The surface area of liquid or solid in contact does not affect vapor pressure. Other factors do have an impact on vapor pressure. Higher density decreases vapor pressure, higher temperature increases vapor pressure and higher intermolecular forces also decrease the vapor pressure.

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.
