Chapter 10 Test

The kinetic-molecular theory explains the behavior of

• gases only.
• solids and liquids only.
• liquids and gases only.
• solids, liquids, and gases.

An ideal gas is a hypothetical gas

• not made of particles.
• that conforms to all of the assumptions of the kinetic theory.
• whose particles have zero mass.
• made of motionless particles.

A real gas

• does not obey all the assumptions of the kinetic-molecular theory.
• consists of particles that do not occupy space.
• cannot be condensed.
• cannot be produced in scientific laboratories.

Which is an example of gas diffusion?

• inflating a flat tire
• the odor of perfume spreading throughout a room
• a cylinder of oxygen stored under high pressure
• All of the them are

By which process do gases take the shape of their container?

• evaporation
• expansion
• adhesion
• diffusion

Why does the air pressure inside the tires of a car increase when the car is driven?

• Some of the air has leaked out.
• The air particles collide with the tire after the car is in motion.
• The air particles inside the tire increase their speed because their temperature rises.
• The atmosphere compresses the tire.

What is the process by which molecules of a gas randomly encounter and pass through a small opening in a container?

• diffusion
• osmosis
• distillation
• effusion

The compressibility of a liquid is generally

• less than that of a gas.
• more than that of a gas.
• equal to that of a gas.
• zero.

Which of the following causes particles in a liquid to escape into a gas state?

• high kinetic energy
• a freezing temperature
• surface tension
• the combining of liquids

Particles within a gas

• do not move.
• vibrate about fixed positions.
• move about freely.
• move slowly
