Front

What is the kinetic theory of matter?

Back

The kinetic theory states that all matter is made up of particles that are in constant, random motion.

Front

Do particles in matter ever stop moving?

Back

No, particles are always in motion.

Front

What type of energy is associated with the motion of an object?

Back

Kinetic energy.

Front

How does the motion of particles differ in solids, liquids, and gases?

Back

In solids, particles vibrate in fixed positions; in liquids, they move more freely but remain close together; in gases, they move rapidly and are far apart.

Front

What happens to the energy of particles as temperature increases?

Back

As temperature increases, the energy of the particles increases, causing them to move faster.

Front

What is the state of matter characterized by a definite shape and volume?

Back

Solid.

Front

What is the state of matter that has a definite volume but takes the shape of its container?

Back

Liquid.

Front

What is the state of matter that has neither a definite shape nor a definite volume?

Back

Gas.

Front

What is the process called when a solid turns into a liquid?

Back
