The effect of temperature on gasses

In this science lesson, we learned all about the effect of temperature on gasses. We did an experiment in which we put a balloon on the lid of a bottle and found that putting the bottle in hot water made it inflate and putting it in freezing cold water sucked the balloon in.

So how did this happen? No, it’s not magic. You see when a gas becomes hot, it expands. This inflates the balloon. And when a gas cools down, it contracts. This causes a vacuum and the balloon is sucked inside the bottle.
