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.

Which of the following is NOT one of the three states of matter?

• Liquid

• Gas

• Solid

What is a key characteristic of solids?

• They can flow

• They have a fixed shape

• They can be compressed

Why can't liquids be compressed easily?

• They have a fixed shape

• Their particles are far apart

• They have no fixed volume

• Their particles are closely packed

Which statement is true about the volume of liquids?

• Liquids have a fixed shape

• Liquids can change volume easily

• Liquids have a fixed volume

• Liquids have no fixed volume

What is a unique property of gases compared to solids and liquids?

• Gases have a fixed shape

• Gases can be compressed

• Gases have a fixed volume

• Gases are rigid
