Practice Assessment: Kinetic Theory of Matter

Front

What does the Kinetic Theory of Matter state?

Back

All matter is made of atoms/molecules that are in constant motion.

Front

What happens to molecular motion when a substance is cooled?

Back

Molecular motion decreases.

Front

How do the atoms/molecules in a solid behave?

Back

They are closely packed and vibrate in place.

Front

How does food dye move through hot water compared to cold water?

Back

It moves faster through hot water.

Front

What happens to water molecules when they are heated?

Back

They increase in speed.

Front

Define 'kinetic energy' in the context of matter.

Back

Kinetic energy is the energy of motion that particles possess due to their movement.

Front

What is the relationship between temperature and molecular motion?

Back

As temperature increases, molecular motion increases.

Front

Describe the arrangement of molecules in a liquid.

Back

Molecules are close together but can move past one another, allowing liquids to flow.

Front

What is the primary difference between solids, liquids, and gases in terms of molecular motion?

Back

Solids have fixed positions, liquids have more freedom to move, and gases move freely and are far apart.

Front

How does pressure affect the state of matter?

Back

Increasing pressure can compress gases into liquids or solids.
