What affects the behavior of gases more than it affects solids and liquids?

• Color and mass

• Shape and size

• Changes in temperature, pressure, and volume

• Chemical properties

What does the kinetic molecular theory explain?

• How to measure pressure

• How particles in matter behave

• Why solids are dense

• How volume changes with shape

According to the kinetic molecular theory, what are all matter made up of?

• Atoms

• Molecules

• Small particles

• Elements

What kind of motion are particles in?

• Circular motion

• Constant, random motion

• Slow motion

• Vibrational motion

When particles collide with other particles, objects, or container walls, what happens to energy?

• It doubles

• It is lost

• No energy is lost

• It creates light

What is pressure?

• The number of particles in a substance

• Amount of force applied per unit of area

• The size of a gas container

• The speed of particles

What happens when particles collide with their container?

• The particles freeze

• The gas turns to liquid

• Pressure results

• The temperature decreases

What happens to the plunger when weight is added to it?

• It lifts

• It compresses the gas in the cylinder

• It evaporates

• It cools the gas

When particles have less space to move, what happens?

• Pressure decreases

• Particles disappear

• Particles collide more frequently and pressure increases

• Volume becomes zero

What causes an increase in pressure in a gas?

• Decreasing the number of particles

• Heating the gas

• Compressing the particles

• Expanding the container
