What did the Magdeburg hemispheric experiment prove?

Hello! That experiment was the first to confirm the existence of air and the pressure of air on Earth! He also demonstrated the difference between vacuum and saturation!

His experiments also showed us that people cannot survive in an environment without air pressure!! Because there is an atmosphere on the earth, but there is pressure on the existence of the atmosphere! That's why we can survive in balance!

The average atmospheric pressure of the Earth is 1 standard atmosphere! And there is air pressure inside the human body! It is directly proportional to the external pressure!

This cancels out the atmospheric pressure of the Earth! So we don't feel the pressure caused by atmospheric pressure! But in a vacuum it's different!

There is no air pressure there! The internal pressure of the person will be squeezed outward! And there is no pressure from the outside world to counteract this pressure, so the blood also becomes foamy!

So the Magdeburg experiment is very meaningful!! Because before that time people couldn't explain whether there was air or pressure on the earth! That experiment proved that!!

Hope mine can help you! Have a nice day!! Thank you!!!

Magdeburg hemispheric experiments have shown that atmospheric pressure is very powerful. Atmospheric pressure is present.

In the experiment, the air in the two hemispheres is pumped out, so that the number of air particles in the balls decreases and decreases. The atmosphere outside the sphere compresses the two hemispheres together, so it is not easy to separate. The more you pull out, the more stressful it becomes.

The atmospheric pressure is high. It took several horses to pull away.

It takes 16 batches of horses to pull away, and the atmospheric pressure is high.

The presence of atmospheric pressure.

Magdeburg Hemisphere (German: Magdeburgerhalbkugeln, English: Magdeburghemisphere), also known as Magdeburg Hemisphere, was a scientific experiment conducted in 1654 by Otto von Glick, then mayor of Magdeburg, in Regensburg (present-day Regensburg, Germany) in the Holy Roman Empire, in order to prove the existence of atmospheric pressure.

The experiment was also known as the "Magdeburg Hemisphere" experiment because of Glick's title. The two hemispheres in which the experiments were conducted are still preserved in the Deutsches Museum in Munich.

In reality, there are also replicas for teaching purposes, which are used to demonstrate the principle of air pressure, and they are also much smaller in size than the hemispheres of those days. If the hemisphere was to be vacuumed, it would take sixteen more horses to pull it apart.

Otto von Glick.

1.Otto von Glick was a German physicist and politician. Born into an aristocratic family in Magdeburg, he studied at the universities of Leibniz and Leiden. He served in the army as an engineer.

2.Otto von Glick invented the piston vacuum pump in 1650 and used this invention to set up a macro burn meter in 1657 and carried out the famous Magdeburg hemispheric experiment, showing the magnitude of atmospheric pressure and pushing.

3.Otto von Glick's research on atmospheric pressure was carried out independently, and it was only after he proved the existence of atmospheric pressure that he learned that Torricelli had made this discovery experimentally 11 years earlier.

4. Otto von Glick's study of vacuum and atmospheric pressure began out of curiosity, and he did not believe in the beautiful language of sophistry and argument, and asserted that "eloquence, elegant language, and the skill of argument are of no use in the field of natural science.""。

What did the Magdeburg hemispheric experiment prove?

1. The Magdeburg Hemispheric Experiment was an experiment conducted by the German physicist Otto von Glick in 1654 to show that the pressure of air itself on an object is substantial. The basic idea of this experiment is to prove the pressure of the air itself by placing two copper hemispheres together with each other facing downward, pumping out the atmosphere in the hemisphere with an air pump, and then measuring the change in the outside atmospheric pressure and the pressure difference between the two hemispheres.

2. The experimental results show that when the two copper hemispheres are completely tightly combined, so that there is no air inside, and all the air is extracted through the small holes in the hemisphere, there is a vacuum between the two hemispheres. At this time, it is difficult to separate the two hemispheres by manpower. This shows that the air exerts pressure on the mass of the object, and the pressure is small and proportional to the air pressure, thus proving that the air itself has mass and pressure.

Grip the notice. 3. Therefore, the results of the Magdeburg hemispheric experiment show that the pressure of air on objects is indeed substantial, which is of great significance for us to deeply understand the principles of physics, especially the formation mechanism of air pressure and air motion.

4. Moreover, the Magdeburg hemispheric experiment also has a wide range of significance for industrial production. Compressed air is one of the necessary conditions for many mechanical processing and production processes, such as painting, welding, purging, etc., which are inseparable from the application of compressed air. Therefore, a better understanding of the pressure of the air itself will help to better grasp the application technology of compressed air and the scientific basis of related fields.

5. In addition, the Magdeburg hemispheric experiment is also one of the important examples of scientific exploration and experimental verification. When people encounter a problem that cannot be explained or solved at present, they can construct scientific hypotheses by designing and implementing experiments under certain conditions, and solve related problems through the verification of experimental data, which is one of the important ways of scientific development and provides important support for practical application.

The Magdeburg hemispheric experiment demonstrated the existence of atmospheric pressure.

On May 8, 654, Otto Gorrick, the mayor of Magdeburg, Germany, put two hollow copper hemispheres with a diameter of more than 30 centimeters close together, used an extractor to extract the air in the balls, and then used two teams of horses to pull the two hemispheres in opposite directions. It took 16 horses to pull them apart, and when the horses tried their best to pull the two hemispheres apart at the end, there was a loud noise. This is known as the Magdeburg Hemispheric Experiment.

In the Magdeburg Hemispheric Experiment, a pair of iron hemispheres, each with a handle attached, and a valve on one side to pump air outward, is a small-scale model of the power of atmospheric pressure. They are known as the Magdeburg Hemisphere, and until now it remains a great presentation tool.

Magdeburg Hemispheric Experiment: The aim was to prove that atmospheric pressure exists and is large.
