What is the science behind the egg in a bottle experiment?

What is the science behind the egg in a bottle experiment?

When air is heated it expands and some of it escapes out the bottle. When the matches go out, the air inside the bottle cools and contracts (takes up less space), thus creating a lower air pressure area inside the bottle than outside. The air molecules on the outside of the bottle push the egg into the bottle.

What physics principle is used to make a surviving egg drop project?

Inertia. Newton’s Laws of Motion are the basic principles illustrated in the egg drop experiment.

What caused the egg to move into the bottle without touching it?

Air pressure is the reason the egg moves into the bottle without us touching the egg. When the air contracts, the air pressure inside the bottle becomes less than the air pressure outside the bottle. This gives the higher air pressure outside of the bottle the opportunity to push the egg down into the bottle.

What happens to the pressure of air inside the bottle when the paper burns?

Because the pressure of the air is pushing it. Before the burning paper was put into the bottle, the pressure of the air inside the bottle was the same as outside the bottle. The burning paper, however, heats the air inside the bottle. This causes the air inside to expand.

What is the effect of the presence of the flame to the air inside the bottle?

Heat produced by the candle flame causes the air inside the bottle to expand.

What forces act on an egg drop?

A falling object (egg) has a downward force acting on it due to gravity. Air resistance acting on the falling egg results in an upward force, and these 2 forces oppose each other.

What are the physics principles?

Basic principles of physics

• Newton’s laws of motion.
• Mass, force and weight (Mass versus weight)
• Momentum and conservation of energy.
• Gravity, theories of gravity.
• Energy, work, and their relationship.
• Motion, position, and energy.

Can crush experiment explained?

A can is crushed when the pressure outside is greater than the pressure inside, and the pressure difference is greater than the can is able to withstand. When the water vapor condensed, the pressure inside the can became much less than the air pressure outside. Then the air outside crushed the can.

How does Newton’s first law relate to an egg drop?

Newton’s First Law, once the egg began moving, it didn’t want to stop. The container of water interrupted the egg’s fall, providing a safe place for the egg to stop moving so you could recover it unbroken. The force of gravity on the egg caused the water to splash out, and the audience burst into spontaneous applause.

How do the gas laws support the results of the egg in the bottle experiment?

According to the ideal gas law, the pressure will rise as the temperature increases so long as the volume remains fixed. This extra pressure will push up on the egg, allowing some air to escape. Consequently, the air pressure inside will be less than the air pressure outside, and the egg will be pushed into the bottle.

Why does an egg in a bottle lower the air pressure?

Most books will tell you that the paper burned up the oxygen, lowering the air pressure inside the bottle, and that the greater air pressure on the outside of the bottle pushed the egg inside. They get the part about the air pressure right, but the lowered pressure in the bottle is not due to burning up the oxygen.

Why did the egg move into the bottle?

Air pressure is the reason the egg moves into the bottle without us touching the egg. Let’s go over exactly what happened. When we started the experiment, the air pressure inside the bottle was the same as the air pressure outside of the bottle because the air inside the bottle and outside the bottle was the same temperature.

How to calculate the atmospheric pressure of air?

So, now we can say that: P 1 + ρgD = P 0 Since air is nearly an ideal gas, we can make the approximation that P 1 V 1 = P 0 V 0 and that means that P 1 = (P 0 V 0 )/V 1. If we put this result in the equation above and solve for P0, we get a relation that will allow us to calculate what the atmospheric pressure is.

Why is it important to study air pressure?

These experiments will help you understand the basic principles that describe how air pressure responds to and is responsible for various phenomena. As you work through the activities, keep in mind that your eventual goal will be to understand the connection between air pressure and hurricanes.
