Understanding the Three States of Matter

This video tutorial explains the three states of matter: solid, liquid, and gas. It covers the characteristic properties of each state, such as rigidity, compressibility, shape, and volume. 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. Examples include a computer for solids, water for liquids, and helium for gases.
