Explanation:

Hot air is lighter and therefore rises higher:
- Hot air is less dense than cold air because the molecules in hot air are further apart. This makes hot air lighter than cold air.
- When Asma filled one balloon with hot vapours from boiling water, the hot air inside the balloon was lighter than the colder air surrounding it.
- Since hot air is lighter, it rises above the cold air, causing the balloon filled with hot air to rise higher than the one filled with regular air.
Therefore, Asma learned from this experiment that hot air is lighter and rises higher than cold air.
