    Answer: Intermolecular forces and tempertaure are the factors which will affect vapor pressure.

    Explanation:

    Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.

    More is the vapor pressure of a substance more will be the kinetic energy present within its molecules. As a result, weaker will be the intermolecular forces present within a substance.

    Hence, more readily the substance will change into vapor state.

    Also, when we increase the temperature for a substance then there occurs movement of the molecules. As a result, collisions tends to increase within the molecules and hence, intermolecular forces become weaker.

    Therefore, temperature will affect the vapor pressure of a substance.

    Thus, we can conclude that intermolecular forces and tempertaure are the factors which will affect vapor pressure.
