Answer 1

Answer:

Explanation:

Vapor pressure is an intensive property, since it only depends on the fraction of the surface particles that can vaporize.

The volume of the liquid might indirectly affect the vapor pressure... in the limit of small headspace.

If the container is closed, and then filled with the liquid, the vapor pressure decreases as the container is filled.

The headspace volume consequently decreases, and since there is less room for gas particles to vaporize and exert a vapor pressure, the vapor pressure decreases until the container is full.

[NOTE: While the container is far from full, this has minimal effect on the vapor pressure.]
