Chapter 11: Problem 34

As the temperature of a liquid increases, what happens to the vapor pressure?

Short Answer

Expert verified
As the temperature of a liquid increases, the vapor pressure also increases due to an increase in the kinetic energy of the particles.

Step by step solution

01

Explain Kinetic Theory

The kinetic theory of gases explains that the temperature of a liquid is directly related to the kinetic energy of its particles. When a liquid is heated, the kinetic energy of its particles increases.
02

Discuss that particles move

As a liquid is heated and the kinetic energy of the particles increases, these particles will move faster and more of them will have the energy to escape the liquid; transitioning to a gas phase.
03

Relationship between temperature and vapor pressure

As more particles escape from the liquid, the concentration of vapor molecules above the liquid increases, resulting in an increased vapor pressure. Therefore, as the temperature of a liquid increases, the vapor pressure increases correspondingly.
