How does vapor pressure change with temperature?

Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase. As the temperature of a liquid increases, the kinetic energy of the molecules also increases. This heightened energy allows more molecules to escape from the surface of the liquid into the vapor phase, resulting in an increase in vapor pressure.

When considering the relationship between temperature and vapor pressure, it's important to understand that higher temperatures generally lead to a greater number of molecules being able to overcome intermolecular forces and enter the vapor phase. Thus, as the temperature rises, the vapor pressure increases. The mention of a decrease in volume is not directly correlated to the relationship between vapor pressure and temperature; rather, it typically relates to changes in gas behavior under pressure.

Therefore, the relationship that as temperature rises, vapor pressure also rises is accurately described, supporting the correctness of the selected answer.
