The Changing Phases of Matter: Moving Particles and Matter

The video tutorial explains that all matter, including invisible matter, is composed of tiny particles such as atoms and molecules. These particles are constantly in motion, vibrating and colliding with each other. The states of matter are determined by the motion and speed of these particles. Understanding particle movement helps explain how matter behaves and undergoes phase changes.

What is the significance of particles being too small to be seen with the naked eye?

Describe the relationship between particles and the phases of matter.
