1 thing i learnt is that sound can be made in space if air is used as a medium.

Another thing i want to learnt is that why Star Wars is fake.

one thing i wish to find out is what happens to the air particles after it is expelled from the object.

1 thing i learnt is that sound can be made in a vaccum even though some people say it doesn't.
another thing i learnt is that

# data[].attributes.body
1 thing I learnt is that technically, there can be sound in space
Another thing I learnt is that sound requires a medium
1 thing I wish to find out is whether there is a limit to sound we can hear

# data[].attributes.body
I learnt that sound waves could technically exist in a vacuum, as long as there is air particles in the certain object.

Another thing I learnt is how it is only 85% true that there are no sounds in space.

I wish to find out if there are certain sounds that we are unable to hear.

1 thing I learnt is that sound requires a medium to travel.

Another thing I learnt is that the grooves on a record are produced through the vibrations of the sound recorded.

1 thing I wish to find out is if age affects how well we hear sounds.

# data[].attributes.body
1 thing i learnt is that when the particles are very spaced out,the pressure is low and it is called rarefaction.Another thing i learnt is that for sound to travel,it needs a medium.one thing i wish to find out is how to reduce the transmission of sound.

# data[].attributes.body
i learnt that it is possible to have sound in space
i learnt that sound needs to start with a medium
i wish to find out why sound is needed

# data[].attributes.body
1 thing I learnt is that sound is able to travel in space, as long as there is a medium of particles to vibrate to transfer sound. The fact that sound is not able to travel in space is wholly based on how sound cannot travel in vacuum. However, space does not necessarily mean vacuum.
Another thing I learnt is that different frequencies of sound are caused by changes in pressure.
1 thing I wish to find out is whether sound is a "useful" form of energy.

1. 1 thing I learnt was that a balloon could make sound when popping in space due to it "bringing" its own matter
2. low and high frequencies of sound
3. is it true that there are some things which are too loud for our ears to hear?

# data[].attributes.body
1 thing I learnt is that sounds do exist in space, but it needs a medium to transmit the sound waves
Another thing I learnt is how vinyl records has grooves that enable the user to play the original song.
1 thing I wish to find out is if I fill the balloon with part air and part water, will I still hear sound?

1 thing I learnt...

Another thing I learnt...

1 thing I wish to find out...

# data[].attributes.body
sound space no sound ?!
sound medium. sound need medium'

why sound...is sound?

# data[].attributes.body
I Learnt that sound can travel through space although a medium is needed.

I learnt that sound is caused by changes in pressure.

I wish to find out if sound can be used to move objects.
