Welcome,
Get ready to see a coin on a bottle jump up and down with this easy science experiment. You will be able to learn about the concept of thermal expansion of gas/air.
We hope you enjoy.
WHAT YOU NEED;
-Hot water
-Bowl
-Bottle (With small mouth)
-Warm water
-Coin
HOW TO DO;
1-Place the bottle in the bowl,
2-Soak the coin in the warm water (We do this to prevent air intake and exhaust),
3-Place the coin on the top of the bottle,
4-Pour the hot water into the bowl carefully and wait a while to see what it will happen (You will see the coin jumping on the mouth of the bottle).
WHY IS THAT?;
Air is a form of matter and it takes up space even in an empty bottle. At the beginning of the experiment the air inside the bottle and the bottle itself are cold. As soon as we pour the hot water into the bowl, the bottle and the air present in the bottle gets heated up. This causes the thermal expansion of the molecules of air. As the air molecules start to expand, these molecules want to come out of the bottle. Once there is more temperature in the bottle, there would more pressure. Since the air molecules are heated up, they try to push the coin on the mouth of the bottle with the pressure created inside the bottle. This pressure makes the coin to jump on the mouth of the bottle. When the water we poured start to be warm, the air inside cools down and thereby making the coin to jump one last time and it stops when the air inside is eventually cool down.
