I already know that vacuum chambers take all the air out of the chamber which makes things shrink

# data[].attributes.body
I know that they take out the air that is inside the glass

# data[].attributes.body
True vacuum chamber has no air in it and makes it hard for things to transmit

# data[].attributes.body
I know that they suck air out of things like glass

# data[].attributes.headline
I already now that no sound will travel through the vacuum because sound doesn’t have a median to travel through.

# data[].attributes.subject
I already now that no sound will travel through the vacuum because sound doesn’t have a median to travel through.

# data[].attributes.body
I know that it is an inclosure where air and other materials are pumped out.

# data[].attributes.body
In a vacuum chamber all the air is removed.

# data[].attributes.body
I know light travels well in a vacuum like space, but sound doesn’t.

# data[].attributes.body
I know that in a vacuum, sound cannot travel, but light can.

# data[].attributes.body
I know that sound cant travel in space but light can. Sound needs a medium.-Brendan

# data[].attributes.body
Vacuum chambers are like space, they have no air in them.

# data[].attributes.body
I know that light waves can travel without a medium (vacuum) and sound waves need a medium to travel.

# data[].attributes.body
I know that in a real vacuum chamber, the air is totally removed. This is in order to have it in affect like it would be in space. It also now has no medium to travel through due to the no air inside of it.

# data[].attributes.body
I know that when you vacuum the vacuum chamber you will remove everything from inside. You will be removing air resistants and everything else in it.

# data[].attributes.body
I know they suck out the air of a chamber creating a vacuum in which experiments can be performed

# data[].attributes.body
I know that a vacuum chamber removes air.

# data[].attributes.body
I know that light can travel fast through a vacuum chamber.

# data[].attributes.body
Ik that light can travel at a super fast speed

# data[].attributes.body
Ik that light can travel at a super fast speed

# data[].attributes.body
The sound doesn’t travel well in a vacuum because there are no molecules to pass through.

# data[].attributes.body
1. I know that vacuums pull in objects/things.

# data[].attributes.body
It a vacuum

# data[].attributes.body
It a vacuum

# data[].attributes.body
I know that it sucks the air out of an object.

# data[].attributes.body
I know that it takes the air out of the chamber

# data[].attributes.body
The vacuum takes out all of the air from the inside.

# data[].attributes.body
Why does light travel through a vacuum but sound doesn't

# data[].attributes.body
I already know that in teh chamber there is no air.

# data[].attributes.body
I know that the vacuum is supposed to have almost no air inside

# data[].attributes.body
I know the vacuum’s job is to pump out the air.

# data[].attributes.body
I want to know what things are altered in a vacuum chamber and how they are altered. For example, does it change the volume of something?

# data[].attributes.body
i know that sound does not travel in a vacuum

# data[].attributes.body
I want to know if the vacuum chamber changes the volume.

# data[].attributes.body
I want to know more about how the sound gets cancelled out when there is no air.

# data[].attributes.body
I want to know what it would do to different items.

# data[].attributes.body
I want to know how the vacuum chamber gets a perfect seal.

# data[].attributes.body
Something I want to know about vacuum chambers is if there was a sponge inside of it would it become all condensed from having the air sucked out of it?

# data[].attributes.body
I want to learn more about why this happens. I want to know it you had a really big speaker would it do the same.

# data[].attributes.body
Why does sound need air to function (be heard)?, but light does not need air to be seen.

# data[].attributes.body
If the speaker was 100000x louder than it is now, would we be able to listen to the music with no air in the vacuum?

# data[].attributes.body
i want to know why we can hear the speaker

# data[].attributes.body
Why does sound need a medium but light does not.

# data[].attributes.body
I know that the sound will be hard to hear.

# data[].attributes.body
Where does the sound go when it is in the vacuum?

# data[].attributes.body
If it  could travel without a medium, would there be a bunch of sounds from space?-Brendan

# data[].attributes.body
I wonder what happens when you put a living organism like a plant or animal  in the vacuum chamber.

# data[].attributes.body
What I now want to know about a vacuum chamber is how did the first person come up with this idea. Also, I would like to know how they came up with a way to replicate this process in the first place.

# data[].attributes.body
I learned that sound doesn’t travel in a vacuum because it doesn’t have a medium to travel through. When the air was pumped out of the glass inclosure, I could hear the volume gradually decreasing as there was less and less air.

# data[].attributes.body
I want to learn what a vacuum chamber can do to other objects

# data[].attributes.body
I want to know how the chamber knows when all the air is out of it.

# data[].attributes.body
I want to know why the light kept shining while the music playing from the speaker couldn’t be heard at all.

# data[].attributes.body
I want to know why the vacuum is able to take everything out including sound.

# data[].attributes.body
I want to know why the you can’t hear the noise anymore once the air leaves the thing

# data[].attributes.body
I learned that not only did the sound not go out of the air. The light did though.

# data[].attributes.body
I want to know why the jar is sealed tight to the platform

# data[].attributes.body
I learned that sound needs a medium to travel through and light does not.

# data[].attributes.body
I want to know why sound does not travel through, but light does? What is the explanation behind this phenomena?

# data[].attributes.body
I wonder why you can’t hear sound but you can see light inside the vacuum

# data[].attributes.body
I learned that when a vacuum chamber takes out all of the air from the inside, you are not able to hear the sound from the speaker, but when there is a medium, you can still slightly hear the music from the speaker.

# data[].attributes.body
I learned if you eradicate the air in a space and make sound, you would hear absolutely nothing. Sound needs a medium.

# data[].attributes.body
I learned that when the median is subtracted then sound is no longer able to travel

# data[].attributes.body
I learned that light doesn’t need a medium to be able to shine but sound does.

# data[].attributes.body
I learned that once all the air is sucked out of the chamber, you can no longer hear the speaker because there is no medium for the sound waves to pass through.

# data[].attributes.body
That light will go threw a vacuum chamber but sound won’t

# data[].attributes.body
I learned that sound can't travel air but light can

# data[].attributes.body
The sound cannot be heard when the bell jar has not air but the light goes through.

# data[].attributes.body
I learned that sound cannot travel through a vacuum

# data[].attributes.body
I learned that for sound to travel it needs a medium and since vacuum chambers take out the air sound can’t travel

# data[].attributes.body
I learned that the sound was very hard to hear.

# data[].attributes.body
I learned that light still travels

# data[].attributes.body
I learned that sound needs a medium

# data[].attributes.body
From seeing the demonstration about how the air was sucked out of the vacuum chamber which made it so that the sound was not able to be heard, I learned that everything needs a medium to travel through. In other words, I learned that when there is a medium present, you can here other things occurring around you.

# data[].attributes.body
I learned that sound needs a medium to travel through for us to be able to hear it.-Brendan

# data[].attributes.body
Why only certain waves travel through a vaccum.

# data[].attributes.body
I learned in order to hear something you need to have a medium in order for it to go through.

# data[].attributes.body
I learned that in order to hear sound you need to have a medium(air)

# data[].attributes.body
I learned that sound can’t travel without air but light can

# data[].attributes.body
I learned that light doesn’t need a medium, but sound does.

# data[].attributes.body
I learned that sound can’t travel with out a medium but light can

# data[].attributes.body
I learned that a vacuum chamber drains out all the sound.

# data[].attributes.body
I learned that sound doesn’t have a medium to travel through in a vacuum chamber that’s why we can’t hear anything.

# data[].attributes.body
I learned that in order for us to hear the sound, there must be a medium for the sound to travel through.

# data[].attributes.body
I want to know why you are no longer able to hear the sound

# data[].attributes.body
I want to know what other things can be affected in a vaccum.

# data[].attributes.body
I learned light travels through a vacuum but sound doesn’t

# data[].attributes.body
I learned that the air in objects makes the object expand.

# data[].attributes.body
That light can travel through a vacuum chamber but sound can not.

# data[].attributes.body
What do scientists do with vacuum chambers?

# data[].attributes.body
I learned that when you have an object in a vacuum chamber and when you start putting air in it the object will start getting bigger because it is putting pressure on the object.
