The Fireproof Balloon |
Materials |
|
8- 2 balloons
- 2 matches - 1/2 cup of water |
Procedure1. Blow up the first balloon and tie it up.
2. Take the other balloon and fill it with 1/2 cup of water. Now, blow it up. 3. Light the first balloon without water. Watch what happens. 4. Now, take the balloon with water and place the match near it. You can see that the balloon does not explode. |
Scientific Theory
For the first balloon without the water the match heated the rubber directly. It caused it to become too weak to resist the pressure. This was because the particles moved really far from each other. For the second balloon with water, instead of heating the rubber, the water was absorbing all of the heat. Water takes a while for it to heat up which, prevents the balloon from popping. This process occurs because of a process called conduction. This is when heat moves from a hotter spot to a colder spot. For instance, the heat from the match moved to the balloon. The particles in the match are moving extremely quickly and are vibrating a lot. Eventually, the particles transfer thermal energy to the balloon.
