What does the Magdeburg hemisphere demonstrate?

The Magdeburg hemispheres are a pair of large copper hemispheres, with mating rims. They were used to demonstrate the power of atmospheric pressure.

What are the Magdeburg hemispheres and how do they work?

Magdeburg hemispheres are two half-spheres of equal size. Placing them together traps air between them. This air is merely trapped, and not compressed, so the pressure inside is the same as the pressure of the atmosphere outside the spheres. That is to say, the air is pushing equally strongly inside as it is outside.

Can you separate two hollow hemisphere?

No, we can not separate the hemisphere if all the air is sucked. It is because when we suck out all air from inside then there create vacuum and thus the pressure differcnce create equal to atmospheric pressure .

Why do Magdeburg hemispheres stick to each other?

Answer. Magdeburg hemispheres are two half-spheres of equal size. Placing them together traps air between them. This air is merely trapped, and not compressed, so the pressure inside is the same as the pressure of the atmosphere outside the spheres.

Who invented the hemisphere?

First, Archimedes imagined cutting a sphere into two halves – hemispheres. Taking one hemisphere gave him a shape with a flat surface to work with – easier than a sphere, and if he could find the volume of a hemisphere, doubling it would give him the volume of a sphere.

Where was Otto Guericke born?

Magdeburg, GermanyOtto von Guericke / Place of birth

Why do Magdeburg hemispheres stick together?

When air is removed from the interior of the hemispheres, however, there is no longer any force pushing outward: the atmospheric pressure outside dominates, pushing the hemispheres together and keeping them from being separated.
