Weather: Measuring Air Pressure

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.

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

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.

i just saw this today and it was so cool

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

thanks alot

Thank you very much

Thank you🤩

Cool

Great thanks

Great !

it was SO COOL!

very nice

I love this video.because it helps to my project

i like it

Air pressure is held on by the curvature of spacetime?

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

hello sir what can we use instead of a ballon?

please can you tell the required materials
