What does the egg in a bottle experiment prove?
What does the egg in a bottle experiment prove?
The answer is all about air pressure. When you first set the egg on the bottle, the air pressure inside the bottle matched the air pressure outside, so nothing happened. When you dropped the burning paper into the bottle, it caused the air inside to heat up and expand rapidly.
Why did the egg fell down inside the bottle?
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.
How do you put an egg in a bottle?
When the can is filled with water vapor, the pressure inside the can is greater than the pressure on the outside of the can. When immersed in water, the water seals the opening and the vapor inside the can condenses, thus reducing the pressure inside the can and causing the can to be crushed.
Why did the egg fell down inside the bottle given that its size is bigger than the bottle opening?
When the air contracts, the air pressure inside the bottle was less than the air pressure outside the bottle. Then the higher air pressure outside pushed the egg down into the bottle.
Why does heating the flask again cause the egg to slide out of the flask?
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.
How do you verify Charles Law?
As the temperature increases, the air inside the flask expands. Afterwards, the gas is cooled in a water bath by maintaining the amount of the air in the flask constant. By measuring/determining the initial and final temperature and volume, we verify Charles's law.
How do you demonstrate Boyle’s Law?
Boyle's law states that at constant temperature the volume of a given mass of a dry gas is inversely proportional to its pressure.
What does the combined gas law state?
The combined gas law combines the three gas laws: Boyle's Law, Charles' Law, and Gay-Lussac's Law. It states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant. When Avogadro's law is added to the combined gas law, the ideal gas law results.
What is air pressure egg demonstration?
In this demonstration, students will use differences in air pressure to force an egg into a bottle. Air expands when it is heated. In this demonstration, the lit matches heat the air inside the bottle. When air is heated it expands and some of it escapes out the bottle.
Why do you think the egg descended inside the bottle when heat was applied?
By using the heating methods, you may find that the egg is being pushed upwards by the increased air pressure inside the glass bottle. Heated air rises and will escape thereby decreasing the pressure inside of the bottle.
How does temperature affect pressure of a gas at constant volume?
The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.
Can crushing experiment?
Usually, the air pressure inside an open can is the same as the pressure outside. However, in this experiment, the air was driven out of the can and replaced by water vapor. Then the air outside crushed the can. When the water vapor inside the can condensed, the can was empty.
