Introduction to Pressure - Force & Area, Units, Atmospheric Gases, Elevation & Boiling Point

This chemistry video tutorial provides a basic introduction to pressure. Pressure is defined as force per unit area. 1 Pascal equals 1 Newton of Force per square meter of area. This tutorial gives you an example of calculating the pressure exerted by a book on the table using the weight force of the book and its cross sectional area. This lecture also discusses the inverse relationship between elevation and atmospheric pressure. As the elevation increases, the atmospheric pressure decreases and the boiling point of water decreases. It's easier to boil water on a mountain since the air pressure is so low but it's harder to boil in a valley that is below sea level. This video also considers the gases that make up the atmosphere. Heavy gases tend to sink down and lighter gases rise. In addition, hot air rises and cold air descends.

I love the example of a pen tip having more pressure than a finger tip because of the area difference.

[@jojoe6969]

thats crazy

[@georgesadler7830]

Professor Organic Chemistry Tutor, thank you for an excellent Introduction to Pressure, Force, Area, Atmospheric Gases, Elevation and Boiling Point in AP/General Chemistry. Learning these concepts is a good way to understand nature on planet earth. Nature is undefeated on planet earth. This is an error free video/lecture on KZbin TV with the Organic Chemistry Tutor.

[@starhubstarhub9940]

Thanks for this video! just started learning this topic, really helpful!

[@rizazo1212]

I've learned so much more about why things are the way they are from this vid. Much love!

[@gudielvega3001]

This video is so helpful thanks for making it

[@JacksonFriday-er8nk]

This is really helpful.

[@Alvin-ez4he]

hey your 22 mins are better than my university thanks.

[@ngohnicoline4510]

Very good teacher

[@shamiraidora8120]

THANKYOUUU SO MUCHHHHHH !!!!!!

[@elizabethbachicha]

At 1:30 the arrow for pressure should point up. When area decreases, the pressure increases. They are inversely related so should point in opposite directions. Either way he explained it correctly.

[@arupshorts1289]

Very slow voice

really very helpful .👍👍😊😊☺☺

1000Gigapascle pressure required how much surface area ?? How much bigger an aneroid barometer cell cylinder made with this much of surface area ?? What type of material are appropriate for this work ???

[@favourchinwokwu8491]

I love the course but ozone is a heavier gas than oxygen, why does it then stay up instead of sinking down

[@anilkumarsharma8901]

What is work done by aneroid barometer in joules???? How many mechanical barometer provides one kilowatt hour energy forever

[@punitranjan227]

Dear sir, I have a question- How can I achieved the pressure that is 10 N/cm square onto a PVC electrical tape by setting a cylindrical tube which is made from material not causing corrosion and also tube will be filled with the appropriate amount of lead shot, to assure the desired pressure. Please tell me the dimensions of the cylinder and the weight of the lead shot.

[@jpintor0583]

Just wanna ask, is (Pa×m² = N) ?

[@arjgaming8653]

Force = Area×Pressure (F = A×P)

[@bihoyebog1413]

How did you get 9.8

[@arniie5288]

Thats the gravitational constant on earth

[@juanabenjamin856]

It's constant of gravity which is either (9.8 or 10)

[@mystic5941]

Btw i cant understand isnt force= mass × acceleration .......weight = mass × gravitional force

[@pew7217]

Weight is force acting on a body due to gravity and its measured in (newtons).

[@amandaparedez8176]

That Greta and everything but where did 9.8 come form ?

[@kellanfeng]

That's the gravitational acceleration of Earth

[@kellanfeng]

9.81 if you want to be specific

[@mypetthepuppy]

How the pressure will be 612.5

[@mypetthepuppy]

How it will come

[@mypetthepuppy]

Also 0.7 0.4 . How to calculate

[@immacdont6291]

1 atm=101.3kpa not pa

[@roshnihassan3948]

I have exam tire and I'm starting it now at 12:20
