Kinetic Theory of Matter

Front

What is the Kinetic Theory of Matter?

Back

The Kinetic Theory of Matter states that all matter is made up of tiny particles that are in constant motion. The speed and arrangement of these particles determine the state of the matter (solid, liquid, gas).

Front

What happens to particles when the temperature of matter decreases?

Back

The particles slow down and move closer together.

Front

What leads to a change of phase in matter?

Back

A change in the amount of kinetic energy.

Front

If the atoms of an object are moving fast, what can we say about its temperature?

Back

The temperature would be high.

Front

What happens to the average kinetic energy of matter when it is heated?

Back

It increases.

Front

What is Kinetic Energy?

Back

The energy of an object as it is in motion.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, the speed of particle movement increases.

Front

What are the three states of matter?

Back

Solid, liquid, and gas.

Front

How do particles behave in a solid state?

Back

Particles are closely packed together and vibrate in place.

Front

How do particles behave in a liquid state?

Back

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