What are the jobs in the bell jar experiment for the foam block and vacuum pump?
In the bell jar experiment, the foam block is used to represent the lifting force acting on an object. The vacuum pump is used to create a low-pressure environment inside the bell jar, causing the foam block to rise as the air pressure decreases, showcasing the concept of buoyancy and air pressure in a visual way.
Experiment to demonstrate that sound need a material medium to propagate?
Take an electric bell and hang this bell inside an empty bell-jar fitted with a vacuum pump (as shown in the following figure). Initially, one can hear the sound of the ringing bell. Now, pump out some air from the bell-jar using the vacuum pump. It will be observed that the sound of the ringing bell decreases. If one keeps on pumping the air out of the bell-jar, then at one point, the glass-jar will be devoid of any air. At this moment, no sound can be heard from the ringing bell although one can see that the prong of the bell is still vibrating. When there is no air present inside, we can say that a vacuum is produced. Sound cannot travel through vacuum. This shows that sound needs a material medium for its propagation.
What can you hear when a bell rings in a vacuum?
In a vacuum, no sound can be heard because sound waves require a medium, such as air, to travel through in order to be heard. Without a medium, there is nothing to carry the sound waves from the vibrating bell to our ear drums.
How did Robert Boyle discover that sound can't travel through a vacuum?
he put his freind in an air le chamber (with out a mask) and asked him if he could hear him. when his friend did not reply he knew that he did not hear hime or that he was dead. Hope it helps!
Why can you hear the whoosh sound when you open a can of vacuum peanuts?
When you open a can of vacuum-packed peanuts, the sudden release of pressure inside the can causes the surrounding air to rush in rapidly. This rapid influx of air creates the 'whoosh' sound that you hear as the can is opened.

Why cant we hear each other on the moon?
The Moon has no atmosphere, only vacuum. There is nothing for the sound waves to travel in.
In the game club penguin how do you turn the sound on to hear the conversation inside the closet?
you cant
If a bell is ringing in a bell jar you cant hear it when the air is pumped out but you see it what differences in properties of sound and light does this indicate?
That sound cannot move through a vaccum.
What would happen if you rang a bell in space?
In the vacuum of space, sound cannot travel because there are no molecules to carry the sound waves. So, if you were to ring a bell in space, you would not hear the sound it produces.
Can you hear anything in outer space?
No, sound cannot travel through the vacuum of space because it requires a medium, such as air or water, to propagate. Astronauts can hear inside their spacecrafts where there is air, but they cannot hear anything outside in the vacuum of space.
What can you hear when a bell rings in a vacuum?
In a vacuum, no sound can be heard because sound waves require a medium, such as air, to travel through in order to be heard. Without a medium, there is nothing to carry the sound waves from the vibrating bell to our ear drums.
Vacuum booster requires too much pedal effort?
Either it is not getting enough vacuum or the booster is going bad. You can sometime hear a whistle inside under the dash if it is leaking.

Why a bell ringing inside a vacuum chamber cannot be heard?
sound needs a medium to travel. material medium is necessary for propogation of sound. in vaccum sound do not travel. that's the reason why we are not able to hear sound in this case. Jordi101
