Temperature plays an important role in how gases behave compared to solids and liquids.

• Gases: When you heat a gas, it gets bigger. Imagine putting a balloon in the sun. It starts to blow up more—this shows how heat makes gases expand!

• Liquids: Liquids also grow a bit when they are heated, but not nearly as much as gases do.

• Solids: Solids mostly keep the same size because their tiny parts are packed tightly together.

In summary, gases change a lot more when the temperature goes up!
