Weather: Measuring Air Pressure

[@laurettecousins6176]

My teacher sent me to watch this video. This is a very good video.

[@ceeyar2003]

me too!

[@pix3lized843]

Thanks for making this video! I needed to understand them better for Physical Science.

[@alialobaidi5472]

Thanks it helped me in my test

Don't forget thermal expansion and contraction of air. Holding the glass warms it up, which expands the glass, and warms the air, which expands that as well. You seal it with a balloon and lay it down, the glass cools and contracts, along with the air, and it reduces volume, causing a vacuum. The same thing is done when sealing mason jars. You can see the same thing sealing hot food in a container and letting it cool, a lot of times it will pop the lid off from the amount of vacuum it pulls after it cools down.

Toothpick is not long enough to give alot of movement. Better to use a longer stick.

A good application of this is the air pressure inside the airplane. Your explanation reminded me about the ear pop. Very interesting demos and I really liked the passion you exhibit to explain these difficult concepts.

[@amberchisholm4342]

i just saw this today and it was so cool

[@cijumathew1963]

Thank you very much

[@ooflord5711]

Cool

[@advaitabhooshan4010]

Great thanks

[@shanumvallikkaparambil2443]

it was SO COOL!

[@اسيهالغامدي-ظ9ع]

Thank you🤩

[@indikapushpa4976]

I love this video.because it helps to my project

[@Topialovesmuslim]

This is gonna help me in my test

[@bhargaviindora1202]

hello sir what can we use instead of a ballon?

[@KoloSokame]

LOVE YOU MAN IM A FAN

[@tuyeimodjeipo8177]

i like it

[@duaymeri]

Hi i know its late but can we put straws instead of toothpick.

[@infodiyorbek]

Great !

[@shaguftaparween8416]

please can you tell the required materials

[@jyotirmoymukhopadhyay8235]

very nice

[@robert2real]

Air pressure is held on by the curvature of spacetime?

[@tanyasharma225]

Nice video

[@barackbuloso2706]

Thank God tomorrow is school if I don't complete this I will be in detention

[@названиедляканала3-х9о]

thanks alot

[@randomstuffwithkori5596]

So I have a question .... if we say air pressure exerts force on all direction y can't we jump from a very high building or mountain then wait for the air pressure to hold us there....I know the effect of gravity but what happens to air pressure here

[@bearwastaken6579]

guess why parachutes work

[@TVTimes-nx6fz]

Thanks sir. Can I know more about weather from you.

Thank you so much for your feedback on our science video. And thanks for spreading science! Please keep in mind our channel, FunScienceDemos, has over 150 science demonstrations for every important idea in science. Here is our channel link: kzbin.info . If you are a teacher, we would love to hear how you are using this video. Science is so cool!

[@rogue1346]

It is the force exerted on a surface by the air above it as gravity pulls it to Earth

[@grahamstudley1374]

him: blue is cool also him: *uses a red balloon*

[@kouchuujin]

This explains my barometric pressure mirgaines visually. Lol

[@shanumvallikkaparambil2443]

wow i try it. that was cool 👍🏻😍😘🥰

[@oliviapowell9694]

can you use selotape instead of glue?

[@jennifpherwaldie9488]

tape can come off

[@liyajohnson4585]

no, tape comes off.

[@steepsy_4106]

in out in out 5:01

[@epicgaming5737]

Nice✌️

[@rajnikumari6124]

Barometer

[@wavyy_and_kudos]

bro am I the only one watching this for homework

[@MahirFadte]

😎👍

[@MintyGuy13]

I made a barometer and it rises inside the car

[@Annreviews]

... got it from link lul

[@fooliosissss]

LOOOOOOOWWWWWWWW pressure

[@cubetist3494]

hi

[@horizontbeskrajneinovacije6440]

Thanks for the video... Great presentation... Air is not pusshing on anything from any direction...? The so called Air-pressure only has the sense within enclosed-system...wherе there is a barier to push-aginst/oppose...? gass/air---expansion... The expansion which occure due to changes in Temperature...? Please STOP spreading misconceptions...and re-record the videos with correct explanations...? That would be great...? Also, great corelations with the physiological-processes...?

[@bearwastaken6579]

guess why air doesn't float out into space smart guy...

[@xanh350]

you showed us how to make the damn thing, but you didn't show us how to measure air pressure that is said to be equal to 101.3 kPa, where did science get this number from, their ass? ive been searching youtube fro an experiment that show me that air pressure equal to 1bar or 101.3 kPa, I still haven't found any.

[@macyus3367]

lol

[@bettystephens1900]

Cool

[@shaguftaparween8416]

please can you tell the required materials

[@dontcare6863]

1 medium clear plastic cup 1 balloon 1 toothpick 1 plastic straw, non-bendable test might be a little late lol

[@shaguftaparween8416]

please can you tell the required materials..

[@connorronaldo]

He did in the beginning of the video
