Gases, like the air around us, are made of tiny particles that are always moving. Because these particles are so small and spread out, we usually can't see them. This activity demonstrates how, even though we can't see air, it takes up space and we can trap it. By using a bag, we can 'catch' the air and observe its properties, proving that even invisible things can have a real presence. This is a simple way to understand the properties of gases!
This simple experiment helps understand the properties of gases, even though they are invisible. By trapping air in a bag, students can observe that air takes up space and has volume. It's a fun and engaging way to learn about the states of matter! 🎒
Match the term with its definition:
