Egg in a bottle

Allison Carranza 10B

How does heat help the egg get into the bottle?

BIG QUESTION

Hypothesis

If we apply heat to the inside of the bottle then the egg will get to the inside because of heat.

Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it.

BACKGROUND RESEARCH

Before the burning paper was put into the bottle, the pressure of the air inside the bottle was the same as outside the bottle.

Air expands when it is heated. If air is heated in a container that prevents expansion, the pressure of the gas increases.

This causes the air inside to expand. When the egg is placed on top of the bottle, it seals the bottle, and the fire eventually goes out.

When the fire goes out, the air inside the bottle cools. As it cools, the air contracts, and the pressure of the air inside the bottle becomes less than the pressure outside.

When the heat source is removed, the air will contract and decrease in pressure. In a container, this causes the outside air particles to push into the container to equalize the pressure inside and out.

MATERIALS

• A GLASS BOTTLE
• HARD-BOILED EGG
• A PIECE OF PAPER
• MATCHES

PROCEDURE

3. Quickly place the egg at the top of the glass container. The egg should be pulled into the container.

1. Light a strip of paper using a match or lighter. 2. Drop the paper into the milk bottle or other glass container you are using.

RESULTS

CONCLUSION

In conclusion the egg served as a seal, preventing outside air from entering and filling the void. As a result, the force of air pressing on the egg from outside the bottle was larger than the force of air pulling up on it from within the bottle, resulting in an imbalanced force. The egg was successfully put into the bottle!
