Why is the bell jar controversial? Scientifically bell jars are used commonly to demonstrate air pressure experiments and their effects. In school bell jars are used to remove air, thus creating vacuum in order to show that sound cannot travel 'within the bell jar while a ticking clock has been placed inside it. The controversy is about bell jars cannot with stand pressures above atmospheric, only below.

Why is a string used in the bell jar experiment?
A string is used in the bell jar experiment to demonstrate vibrations of sound waves. When the string is plucked, it vibrates and creates sound waves that can be seen and studied under a bell jar with a source of vibration like a tuning fork. This experiment helps visualize how sound travels through a medium.
When the air in a bell jar containing a ringing bell is removed the sound decreases. why?
When the air is removed from the bell jar, there is no medium for the sound waves to travel through, resulting in the decreased sound. Sound waves require a medium, such as air, to transmit vibrations. Without air in the bell jar, the sound waves cannot propagate as effectively, leading to a decrease in the sound.
Why cant you hear a bell inside of a vacuum jar?
Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
Why does an inflated balloon inflate inside a bell jar?
An inflated balloon will inflate inside a bell jar because the air pressure outside the balloon is reduced when the bell jar is sealed. This creates a pressure difference between the inside and outside of the balloon, causing the air inside the balloon to expand and inflate it.
Why would a balloon inside a bell jar inflate when pressure is decreased within the jar?
The balloon exists in a separate pressure system from the bell jar itself.As the balloon is open to the surrounding air, the pressure within the balloon is 1 atm (1 atmospheric unit of pressure = 105 Pa).When pressure is decreased within the jar, the pressure within the jar decreases to a value lower than 1 atm. Therefore, to counter the low pressure created in the jar, the atmospheric air moves into the balloon and pushes the balloon into the jar to attempt to equalize the pressure in the balloon and in the jar. Therefore the balloon inflates.
When was The Bell Jar created?
The Bell Jar was created in 1963.
What does the rubber sheet on bell jar do when pulled down?
When the rubber sheet on a bell jar is pulled down, it creates a vacuum seal between the bell jar and the surface it is placed on. This vacuum seal allows for the removal of air from within the bell jar when connected to a vacuum pump, creating a vacuum environment inside the jar.
In the story 'The Bell Jar' Why is the story 'The Bell Jar' and what is the significance of it?
It is called the bell jar because Esther says that she feels that she feels almost as if she has been stuck under a bell jar. Also, the story is comparing the effects of being under a bell jar, which would distort the view/perspective of one beneath it, to the effects of being depressed or living in a world one does not fit in with
What are the release dates for Bell Jar - 2013?
Bell Jar - 2013 was released on: USA: 21 April 2013
Describe the bell in a bell jar with vacuum experiment?
A bell jar is a piece of laboratory equipment used for creating vacuums.[1] It can be similar in shape to a bell, and can be manufactured out of a variety of materials (ranging from glass to different types of metals). A bell jar is placed on a base which is vented to a hose fitting, which can be connected via a hose to a vacuum pump. By pumping the air out of the bell jar, a vacuum is formed.
What is the function of bell jar?
A bell jar is a glass dome that can house delicate objects or serve as a vacuum if the air is sucked out.
What actors and actresses appeared in Bell Jar - 2013?

Will you hear anything when you set the alarm clock on the table and place it under a bell jar?
yes, because the bell jar will vibrate
What is the foam block for in the Bell Jar experiment?
The foam block is used to support the bell jar and create a seal with the baseplate. This helps to create a vacuum inside the bell jar by preventing air from entering or escaping during the experiment.

How is the bell jar system like the respiratory system?
The diaphragm in bell jar model is pulled down during inhalation, whereas in actual respiration, the diaphragm is flattened.The wall of the bell jar is rigid, whereas the thoracic wall is flexible and changes during breathing.the bell jar cavity is filled with air, whereas the thoracic wall is filled with body fluid.
