Question

Which factors affect the vapor pressure of a liquid?

1) Intermolecular forces of attraction within the liquid
2) The volume and/or surface area of the liquid present
3) The temperature of the liquid

Answer 1

The vapor pressure of a liquid is affected by intermolecular forces, temperature, and the volume/surface area of the liquid.

Step-by-step explanation:

Vapor pressure is the pressure at which a gas coexists with its liquid phase. It is influenced by several factors:

1. Intermolecular forces: Strong intermolecular forces impede vaporization and result in a lower vapor pressure, while weak intermolecular forces allow for easier vaporization and result in a higher vapor pressure.
2. Temperature: As the temperature increases, more molecules have enough energy to escape the liquid phase and enter the gas phase, leading to an increase in vapor pressure.
3. Volume and surface area: These factors do not directly affect vapor pressure, but they can indirectly influence it by affecting the rate at which molecules evaporate and escape from the liquid phase.
