Question

question 1
what happens to the vapor pressure as the temperature of the liquid increases?
○ vapor pressure is not affected by temperature.
○ the vapor pressure will compensate until it becomes equal to the pressure of the surroundings.
○ the vapor pressure decreases.
○ the vapor pressure of the liquid increases.

Explanation:

To determine the answer, we recall the concept of vapor pressure and temperature. Vapor pressure is the pressure exerted by vapor in equilibrium with its liquid phase. As temperature increases, the kinetic energy of liquid molecules increases, so more molecules escape into the vapor phase, leading to an increase in vapor pressure.

• The first option is incorrect because temperature does affect vapor pressure.
• The second option describes a concept related to boiling (vapor pressure equaling atmospheric pressure), not the general relationship between temperature and vapor pressure.
• The third option is incorrect as vapor pressure increases with temperature, not decreases.
• The fourth option correctly states that as the temperature of the liquid increases, its vapor pressure increases.

Answer:

The vapor pressure of the liquid increases.
