Let’s Review

States of Matter Particles Movement/Kinetic energy

Kinetic Theory of Matter

All matter is made of particles. These particles are always moving*. As temperature increases, particle movement increases. Solids, liquids, gases have differentparticle freedom and motion.

*energy of moving matter is called Kinetic Energy

A particle of matter

Kinetic Energy of particles determines the state of matter

Solids have the least Kinetic Energy and gases have the most.

How can you use a bottle of cola to demonstrate the relationship

between Kinetic Energy and state of matter?

Explain your answer

Quiz1. Which state of matter has the most kinetic

energy?

2. What type of energy can increase the movement of particles?

3. Explain how water particles (molecules) move as a solid (ice). How can you change the ice to a liquid? How do the particles move in a liquid?

Gases have the most kinetic energy. The particles are moving faster, they have more energy.

Kinetic Energy can increase the movement of particles.

The solid particles move slowly and are closer together. When kinetic energy is added to these particles (increasing temperature), they begin to move faster and to spread apart.The liquid particles move faster and spread more apart than solid particles.
