States of Matter (solids, liquids and gases)

This video tutorial explains the three states of matter: solid, liquid, and gas. It provides examples and describes the characteristic properties of each state. Solids have closely packed particles, making them rigid with a fixed shape and volume. Liquids have particles that can move around each other, allowing them to flow, with a fixed volume but no fixed shape. Gases have particles that are far apart, making them compressible with no fixed shape or volume.

What is an example of a gas and why is it used in party balloons?

Explain why gases do not have a fixed shape or volume.
