Here's what I've understood: if there's a high pressure, there will be winds moving towards the low pressur area. and since there's low pressure, there will be precipitation eventually. However that won't be happening in the high pressure area becuz of descending air. Hence it will be a clear day maybe slightly foggy but no rain as the air in sinking down and not rising to to precipitate.
How much negative pressure exists which can hold a kg weight inside the tube ?? Can you provide every equations which governed mechanical barometer Which shows efficiency of the mechanical barometer as an engine working under the atmospheric pressure Sooon my gas cylinder is running out so how i cook my food in a lockdown situation So we needed atmospheric pressure free energy as a source of heat to cook the food
sir if there is no mercury in the "dish" would the mercury in the glass coulmn fall much more than 760 m.m mark? if we are taking a 1000 m.m long tube contain mercury
Okay but why mercury, I'm fascinated by mercury.you have to have it at a certain temperature or it's a solid, why not make some sort of soldier suite that can have medal as liquid moving with you but then become solid by some catalyst, what if you made an impact obsorbing cell that cooled upon impact and solidified encasing the organic tissue in an impenetrable barrier¿
Mercury is the most dense liquid at room temperature, so you don't need a very large column to make an effective barometer. Any other liquid would require a device meters tall, therefore way too large to be practical.
Short and concise!
this helped me when my biology text book couldn't
I passed my exam by learning this from you!!
Congrats.
Yesss thank you so much! Was looking for this
Explained how barometer works within 2 mins 👌👌👌 amazing
Thanks! I don't think there's another video that explains it as well in less than 2 minutes!

Really helpful...... Last minute saver
thank you i have a home school lesson on this :)
thank you for the video :) its the only video that made sense to me out of 10 other videos.
Awesome! I'm glad that it helped you.
@TheScienceClassroom pls reply to this comment. I watched your video after 10 yrs and it helped me so much.
Finally makes sense
okay.. what you didn't talk about was hot and cold air.. is not cold air heavier and causes high pressure? how does that lead to good weather?
True, logic dictates high pressure = cold air = heavy rain
Temperature is the main determining factor for air density

Youer vido was great. Thank you for taking time out of youer day to teach us somthing! Verry helpful!!!
wow so short but holds a lot of info
Simple and coool!
thank-you ! simply and well explained. easy to understand compared to all the other sources I checked out
Wonderful video brother 👏
Cheers!🤗
How barometer measures atmospheric pressure?????
Very well explained, and presented.. thanks a lot.
That really helped me out!
Great video!!!
🤗
Thanks this was easy to understand
wow thanks for the explanation
👍😃
Can you buy brand new barometer? When I try to shop online all I find is antics
Thank you !!!
Finally I get it now. 🙌
thanks solo much, got my geography coursework exam tomorrow and this was very useful
Thanks for this brother, the use of a barometer became more clear to me. May you always follow GOD's guidance

Your screwed buddy
u made it simple and easy thanks alot!
How does a barometer work?
@@Clawwingo can you give every equations which governed mechanical barometer so we got a model which turned 10 ^14 kg pressure into electricity
@@anilsharma-ev2my XD
Does the height change with the width of the tube or the dish? or the volume of the total mercury?
no it doesnt, if it has enough tho
yea thank you
thanks
sir if there is no mercury in the "dish" would the mercury in the glass coulmn fall much more than 760 m.m mark? if we are taking a 1000 m.m long tube contain mercury
Idk
it will, because there is not much mercury in it
You explained it very fast😅😅😅😅🤒🤒
Oh .........wow. Yes
excellent
No bullshit. 👍
Concise.
O.M.G THANK YOU I FINALLY GET IT NOW❗️🎀🎀
Watch TED-Ed s vid
Much better
I hate it
😟
