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
When the air in a bell jar containing a ringing bell is removed the sound decreases. why?
Sound cannot travel in a vacuum.
What is an experiment to demonstrate that sound requires a medium to travel?
Making some sound (ringing a bell, dropping an object, etc.) inside a vacuum.
Can sound wave pass through in vacuum?
No - sound wave cannot pass through "vacuum". It was Robert Boyle, English scientist who proved in 1960 that sound waves need to pass through a medium to transmit sound. This can be tested as follows: Place a bell inside a chamber and slowly start evacuating air from the chamber. It can be seen that sound of the bell is slowly becoming softer, until there is absolutely no 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.

Where is the vacuum line on a 96 s10 blazer the one in the fuel spider?
It doesn't have or need a line connected to it. The spider is inside the vacuum chamber.
Why electrons microscopes cannot be used to view the structure of living cells?
Spicemen must be placed in a vacuum chamber. Since living cells cannot survive in a vacuum, they cannot be viewed using elctron microscopes.

Where can one purchase a chamber vacuum cleaner?
A chamber vacuum cleaner can be purchased at Amazon, eBay or other second hand stores. There are many popular brands of chamber vacuum cleaning including Samsung.

When you release a gas in a vacuum chamber does it immediately drop to the floor?
When you release a gas in a vacuum chamber, it immediately drops to the floor because of its density. _______________________________________________________ I expect that the gas will expand to fill the whole volume of the vacuum chamber.
How can a metal film be applied to a plastic product?
There are two ways; 1) Plastics can be metalized on the surface by the process of vacuum metalizing, in which metal filaments are vaporized on to the plastic surface and the condensed in a vacuum chamber. 2) Sputtering, the metal is ionized in a vacuum chamber by an electrical discharge between two electrodes, a metallic cloud forms inside the chamber and fogs the plastic parts with a thin layer of metal .

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 is the principle of a thermos flask?
If you call it by its correct name "vacuum flask" the principle becomes clear. The flask consists of an inner and outer chamber, the space between the chambers is a vacuum. A vacuum cannot conduct heat, hence no losses between the two chambers.
