1266 - What is the relationship between the pressure and volume of a given amount of gas in a closed container at constant temperature?

Imagine you have a balloon with air inside it. The pressure is like how tightly the air is squeezed in the balloon, and the volume is like how big the balloon is.

When the temperature is the same (like it's not getting hotter or colder), if you make the balloon smaller, the air gets squeezed in tighter, so the pressure goes up.

If you make the balloon bigger, the air has more space to spread out, so the pressure goes down.

So, in simple words, the relationship is this: If the volume (size of the balloon) goes down, the pressure goes up. If the volume (size of the balloon) goes up, the pressure goes down. This is called Boyle's Law.
