Question: What happens to the vapor pressure of a liquid as temperature increases?

Options:

Correct Answer: It increases

Solution:

As temperature increases, the kinetic energy of the molecules increases, leading to an increase in vapor pressure.

What happens to the vapor pressure of a liquid as temperature increases?

Step 1: Understand that vapor pressure is the pressure exerted by the vapor of a liquid in a closed container.
Step 2: Know that temperature is a measure of how hot or cold something is.
Step 3: Realize that when the temperature of a liquid increases, the molecules in the liquid move faster.
Step 4: Recognize that faster-moving molecules have more energy, which allows some of them to escape from the liquid into the vapor phase.
Step 5: Conclude that as more molecules escape into the vapor phase, the vapor pressure increases.

Vapor Pressure – The pressure exerted by a vapor in equilibrium with its liquid at a given temperature.
Kinetic Energy – The energy that molecules possess due to their motion, which increases with temperature.
Temperature Effect – The relationship between temperature and vapor pressure, where an increase in temperature leads to an increase in vapor pressure.
