💨 States of Matter: Gases
Explore the unique properties of gases and understand how they behave differently from solids and liquids. This quiz focuses on particle movement, pressure, diffusion, and how gases respond to changes in temperature and volume. Through real-world observations and scientific principles, you'll discover why gases fill any container and how we use them in everyday life. **What you'll learn:** - How gas particles move and are spaced compared to solids and liquids - Why gases have no fixed shape or volume - How diffusion and expansion occur in gases - The effects of temperature and pressure on gas behaviour - How to identify common gases and their properties
