What is Boyle’s Law?

Boyle’s Law is about how gases behave when you change their space or pressure.

Imagine you have a balloon full of air, that's like a gas in a container. Now, if you squeeze the balloon, it gets smaller (less space), and the air inside pushes harder (more pressure). If you let go, the balloon expands again (more space), and the air doesn’t push as hard (less pressure).

Think of a soda bottle with some air in it. When you squeeze it, the air molecules are packed closer together, that’s why the bottle feels harder. If you stop squeezing, the air spreads out again, and the bottle gets easier to press.

This is what Boyle’s Law says: if the temperature stays the same, when the space a gas has goes down, its pressure goes up, and vice versa.

It's like having a group of friends in a room. If you make the room smaller (less space), they have to stand closer together (more pressure). But if you give them more room (more space), they can spread out (less pressure).
