Question

1. describe the effect that increasing temperature has on the vapor pressure of a liquid.

Explanation:

Vapor pressure is related to the tendency of liquid molecules to escape into the gas phase. Increasing temperature provides more kinetic energy to liquid molecules. More molecules gain enough energy to overcome intermolecular forces and enter the vapor phase, thus increasing the number of vapor molecules above the liquid. This leads to an increase in vapor pressure because vapor pressure depends on the concentration (or number) of vapor molecules exerting pressure.

Answer:

Increasing the temperature of a liquid increases its vapor pressure. This is because higher temperature gives liquid molecules more kinetic energy, so more molecules can escape the liquid's surface to become vapor, increasing the number of vapor molecules and thus the pressure they exert (vapor pressure).
