Answer:
When the air cools down, the molecules also settle down in the tube and they contract.

Answer:
Air expands when it is heated, it spreads out and either fills a larger space or raises the pressure in a closed space. So we can say that air on becoming hot occupies more space. Since the particles move away from each other, the air becomes less dense and lighter in weight.
If we take out the boiling tube from hot water and allow it to cool, then after some time, the balloon will get deflated . This is because the air present in boiling tube and balloon contracts on cooling due to which its volume decreases and balloon gets deflated.
