He is most recognized for his so-called Magdeburg experiments, in which two copper hemispheres were placed together, the interior evacuated, and two teams of horses were unable to pull the evacuated hemispheres apart until the air was readmitted.

What experiment did Otto von Guericke use to prove the power of air pressure?
To prove that a vacuum and atmospheric pressure existed, von Guericke performed one of his most well-known experiments: the Magdeburg Hemispheres. Von Guericke placed two 20-inch copper hemispheres together and used his pump to remove the air inside, creating a sealed vacuum.
How did Otto von Guericke discover the air pump?
In the 1640s, he began trialing water pumps for firefighting. In about 1647, Guericke began modifying water pumps. He discovered that he could use a pump to remove air from a sealed metal or glass jar. He had produced the world's first vacuum pump.
What experiment did Otto von Guericke perform in front of Emperor Ferdinand?
In 1654, in a famous series of experiments that were performed before Emperor Ferdinand III at Regensburg, Guericke placed two copper bowls (Magdeburg hemispheres) together to form a hollow sphere about 35.5 cm (14 inches) in diameter.
What did the Magdeburg experiment demonstrate about air pressure?
They were used to demonstrate the power of atmospheric pressure. When the rims were sealed with grease and the air was pumped out, the sphere contained a vacuum and could not be pulled apart by teams of horses in a famous first public demonstration in 1654.
What is the experiment to prove air has mass?
When you place a deflated balloon on one side of a lever balance and an inflated balloon at the other end, you will see that the side with the inflated balloon tilts downwards. This shows that air has mass.
What is the aim of air pressure experiment?
The goal of this science fair experiment is to demonstrate the effects of air pressure on objects and analyze applications of air pressure principles.
What is the theory of air pump?
When the piston is pulled up, air gets sucked into the pump through the inlet. The pump chamber depressurizes as it fills with air. When the piston is forced down, the air becomes compressed and closes the inlet. Then the air flows out from the outlet.
How was the first air pump invented?
The first rudimentary air pump—a sort of syringe—was developed c. 1650 by Otto von Guericke (1602-1686). He used it in his celebrated "Madgeburg hemispheres" experiment to demonstrate that two metal hemispheres, when joined together and evacuated, required the force of at least sixteen horses to be pulled apart.
What is the science behind air pump?
An air pump is a device which is used to move and pressurize air. If this air is contained inside a container of fixed volume, pumping more air into it affects various measurable properties of the air, such as pressure and temperature.
How does the collapsing can experiment work?
When the can was filled with water vapor, you cooled it suddenly by inverting it in water. Cooling the can caused the water vapor in the can to condense, creating a partial vacuum. The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it.
Can you crush a can using air pressure?
Place the can on the hot plate and allow the water to heat. Once Steam is visible from the top of the can, quickly with gloves or tongs, flip the can upside down into the bowl of water. If performed correctly the can will be crushed by the atmosphere.
Who first experimentally measured the atmospheric pressure?
Torricelli then went on to describe how he made the first barometer and how he recognized that it was the weight of the air that supported the column of mercury. He took a glass tube ∼2 cubits (∼110–120 cm) long and filled it with mercury (FIGURE 3).
How will you prove by an experiment that air exerts pressure?
Take a tin-can having air tight cap (screw cap). Remove cap and boil some water in it, so that steam comes out and in this way air from inside goes out. ... We see the can crumbles due to air pressure from outside. This proves that air exerts pressure.
Why do Magdeburg hemispheres stick together?
With almost no outward pressure from inside, the two hemispheres are pinned together by the enormous inward pressure from the surrounding atmosphere.
What is a simple experiment to prove air has weight?
Procedure - An inflated balloon is placed on one side of a simple scale, and the scale tilts towards one side. Observation - The balloon has mass which makes the scale tilt. Conclusion - Air has mass.
What experiments prove air exists?
You can prove air exists by blowing up a balloon. By doing this, it proves that air has weight and air takes up space. Lastly, air is just made up of mainly nitrogen and oxygen. These things all prove that air exists.
How did they prove gas has mass?
After mixing the vinegar and baking soda, the gas from the pitcher will be “poured” into one of the paper bags, which will cause the one end of the scale to drop, despite the fact that no visible substance was poured into the bag. This proves that gas does have mass and that it is heavier than oxygen.
How will you prove by an experiment that air exerts pressure?
Take a tin-can having air tight cap (screw cap). Remove cap and boil some water in it, so that steam comes out and in this way air from inside goes out. ... We see the can crumbles due to air pressure from outside. This proves that air exerts pressure.
What was Otto von Guericke known for?
Otto von Guericke (November 20, 1602, Magdeburg – May 11, 1686, Hamburg) was a German physicist, engineer, and natural philosopher who invented the first air pump and used it to study the phenomenon of vacuum and the role of air in combustion and respiration.
Who first experimentally measured the atmospheric pressure?
Torricelli then went on to describe how he made the first barometer and how he recognized that it was the weight of the air that supported the column of mercury. He took a glass tube ∼2 cubits (∼110–120 cm) long and filled it with mercury (FIGURE 3).
What did Boyle's experiments help people understand about air?
Every general-chemistry student learns of Robert Boyle (1627–1691) as the person who discovered that the volume of a gas decreases with increasing pressure and vice versa—the famous Boyle's law.
What is the theory that explains air pressure?
Kinetic Gas Theory
These particles bounce around colliding with one another as well as the walls of the container. The net effect of these collisions with the walls of the container exude a force over the surface area of the container, and thus a net pressure can be measured.
What is the evidence to prove that air is present everywhere?
Air is everywhere! You might not be able to touch it or see it but it is all around us. Though invisible, you can easily see that air takes up space when you blow up a balloon. You can see the movement that it creates when a breeze blows through the leaves on a tree.
How was the first air pump invented?
The first rudimentary air pump—a sort of syringe—was developed c. 1650 by Otto von Guericke (1602-1686). He used it in his celebrated "Madgeburg hemispheres" experiment to demonstrate that two metal hemispheres, when joined together and evacuated, required the force of at least sixteen horses to be pulled apart.
Why was the air pump created?
invention by Guericke
… philosopher who invented the first air pump and used it to study the phenomenon of vacuum and the role of air in combustion and respiration.
Who discovered the formula of pressure?
This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant. The relationship was also discovered by the French physicist Edme Mariotte (1676).
Who invented the first air pressure instrument?
Although he made important contributions to the field of mathematics, Evangelista Torricelli is best known for his invention of the barometer. Born in Faenza, Italy, on Oct. 15, 1608, he began his education there and later (around 1630) studied in Rome.
Who invented the concept of pressure?
Blaise Pascal (1623–1662) was a French mathematician, physicist and philosopher. He developed the modern theory of probability. He also formulated the concept of pressure (between 1646 and 1648) and showed that the pressure in a fluid is transmitted through the fluid in all directions (i.e. Pascal's law).
