Boyle's Law Demonstrations 

Who's here becuase of school ?

Hello! Thanks for making the video :) Unfortunately the narration makes an error! The narrator states that as the vacuum is created in the jar, the pressure outside the balloon is greater than the pressure inside the balloon, causing the balloon to expand. In fact, as you create a vacuum, you're lowering the pressure outside the balloon causing the balloon to expand. Please fix!

This is a great demonstration of Boyle's Law. Thank you for uploading this very informative video.

I calculated that another way to express that as many times as the volume decreases that many times pressure increases is pressure equals amount of matter divided by volume.

I can't believe you didn't show increase of pressure for shaving cream. Good video, though. Thanks from Texas. Praying for your state during this hurricane. Can't remember the name. -- don't watch TV much.

How does it expand?

what we need to do this experiment???? please help us

I'm pretty sure this is Matthew McConaughey

can someone please Describe and explain the demonstration in 3-5 sentences I need help

i hope everyone’s having fun in school

I agree the effects are cool but the explanation isn't good. Just like the college physics I suffered through twenty years ago. Physicists think what they are saying is super obvious but to people who don't have this intuitive feel for things like vacuum volume pressure whatever.... it just makes my brain tie in a knot. Slow down and explain! I see that the chick is expanding - are the air molecules separtaing more because there are fewer air molecules in the jar with the vacuum? I think it is the thing with the jar - a fixed thing that is mixing me up...... that volume can't change. So we are looking at the volume of the things inside the jar, ignore the jar, for the Boyles law thing. Non physicists have to think this through slooooowly. Physics profs just droned from one thing to the next, to the point that then NO ONE CARED. I love youtube though, at least it gives us a chance! School is obsolete!

Well done

how it is applicable in lungs , respiration . can anyone tell ? please

Wow im amazed

Nice educational video but I need experiment more on gaseous law allthose

Good job

sweet

Very very very very very good

Nice experiments

Clear definition

yes i think he mean decrese, the P out the ball is decresing because the vacum he is creating,, lets say from P=1 atm to P=0.5 atm, so inside the ballon because the initial P is also =1 atm, that presure tries to be like the P outside,, Because the boyle mariotte law, at a T=cst, the volume inside the ballon, increse so the the P decrease, so the P inside goes from 1 to 0.5 for ex., thats the explanation :)

Nice

Thanks 👍

it's good

Wow

👍👍

Boyle's law states this is true, at a CONSTANT TEMPERATURE. But if the volume of air expands wouldn't its temperature go down instead of stay constant?

You mean you pump out the air in the jar, or from the jar? 'coz you can't be absent in class, but from class 'no??

HEY GUYS LETS START EPICALLY GAMING

NCSSM alum watching this video as a part of my CHEM 102 class at UNC! Hah.

noice👍

thats cool

I think the narrator left out some qualifying words. It would have been more clear if he had said: [Before a vacuum is applied] "the pressure outside of the balloon is greater than the pressure inside" [the balloon]. Also, I think describing the balloon as "trying" to equalize the pressure is a bit misleading. The balloon expands without effort on its part, and it could be possible to expand it to the extent it has more internal pressure than the outside if it does not break {Also written as a reply}

thanksssssssssssss

Ay yo me right here😂

This is so confusing
