Question

You are given a fully blow ballon, a tube of hot, water, and a tube of ice-cold water. Using these items, explain how you would show that expands on heating and contain when it's cool down​

Answer 1

Answer:

Air expands on heating. Why does this happen? It is because the particles of air on becoming warm, move away from each other and take up more 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.

As a result, warm air rises up. On the contrary, on cooling the particles of air come closer to each other. Due to this, the volume of air becomes less, the air becomes more dense and heavier. This can be demonstrated by a simple activity.

➢Take an empty bottle, attach a rubber balloon to its neck. Initially, the balloon is deflated. Place the bottle in a container filled with boiling water. After some time you will notice that the balloon gets inflated.this happens because of the air inside the bottle expands on heating and it fills the balloon. Take out the bottle out of the container and allow it to cool itself. We will notice that the balloon gets deflated and it collapses.
