Graham's Law of Effusion
HTML-код
- Опубликовано: 26 сен 2024
- This chemistry video tutorial provides a basic introduction into Graham's Law of Effusion. It explains how to use it to calculate the rate at which a gas effuses out of a container as well as the time it takes for a sample to completely effuse from the vessel. In addition, it discusses how to determine the identity of the gas by calculating the molar mass.

This man is just showering us with constant updates and I'm loving it
i realize I am kinda off topic but do anybody know of a good place to stream new movies online ?
@Garrett Mateo lately I have been using Flixzone. You can find it by googling =)
@Garrett Mateo I watch on FlixZone. Just google for it =)

Professor Organic Chemistry Tutor, thank you for a short and sweet video/lecture on Graham's Law of Effusion in AP/General Chemistry. According to the history books on Chemistry, during World War II, Graham's Law was applied to a rather complex chemical problem. It became necessary to separate U-235, which is fissionable, from the more abundant isotope of uranium, U-238. Since the two isotopes have identical chemical properties, chemical separation was not feasible. Instead, an effusion process was worked out using uranium hexafluoride, UF6. This compound is a gas at room temperature. Preliminary experiments indicated that u-235 could indeed be separated from u-238 by effusion. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
This is what I was planning to learn tomorrow thank you organic chemistry tutor........
3 years ago and it's still very valid
Thanks for saving lives organic tutor🙏
I love the way of you..
I mean no matter what you keep uploading videos ..
Love you bro it helps me a lot
Thanks to your videos.I learn a lot especially chemistry.
This man just helped me in doing my chemistry assignment
Actually the formula in the thumbnail is not correct it’s supposed to be R1/R2=square root of M2/M1 cause the molar mass of certain elements is inversely proportional to its rate of effusion, just sharing ya know 🥰✌🏼
Yep .. infact that's why I even opened the video cos it was given wrong
Uh it still same
Caus it doesn't matter whether it's up or down but it has to be inversely proportional
It's the same thing🤦🤦 geez
You’re the best keep it on ❣️
Amazing..this helps allot.. 👍👏🙏
this, as well as your other video on graham's law of effusion, really helped me! i was strugglign to tell when i needed to use the t1/t2 = root m1/m2 and when i needed to use r2/r1 = root m1/m2 for a question on finding t, but after watching and rewatching these videos (As well as reading from a few other tutorial websites), i've come to understand that it depends on whether the volume of the two gasses is the same. if it's the same, use t, if it's different, use r to solve for t.
hi what do u mean by using r to solve for t if they are different ,how?
@@jazzminemungai I'm sorry, I learned about this topic 5 months ago and it's now left my brain completely and I have no idea now XD That's the beauty of cramming amirite.
How will i know which gas comes first
Sir pls upload folding and symmetry in circuits sir
Good explanation
Wrong equation at video start. It brings up the wrong equation on google images because of this video. Having the top search result for Graham's Law, and having the subscripts wrong, is pretty bad.
Hi I have a question how do we know which one to put in each formula. I mean how do we know which gas to put above and which to put below or does it not matter? urgent hv an exam on monday
they are indirectly related. Whatever is on top on one side goes on the bottom on the other side and vice versa
@@mirandazapata9691 thank u lol
@@elileoci9173 how do I know then that this is supposed to go on top
Great vid. Thanks! Do u know if the effusion rates changes if the ratio of mols is diffrent from 1:1?
Like if i got a ratio of 2:1 does its effect the ratio?
Thank you so much 😍
The formula written on the thumbnail is wrong.
noticed this too, its at top of google search as well
@@arc9171 yeah this is a HUGE problem - please fix!!!!!
How did you get the molar mass. Sorry I'm a bit confused
I wanted to become the best , prominent Neurosurgeon
Have u seen 'The Doctors' 😅
PLEASE PLEASE PLEASE FIX THE THUMBNAIL! ITS THE FIRST RESULT ON GOOGLE SEARCH AND IS EXTREMELY MISLEADING!
Change the thumbnail it’s wrong
It's lovely.
The thumbnail shows wrong formula, pls fix that
1st view
Aye jit, you got this shit wrong my guy
the thumbnail is confusing me and i'm not sure which way is right
The process he shows in the video is correct
The thumbnail is the mistake
2nd comment
That's math
50 cm cube of ethane effuses in 10 seconds what time will it take for 25 cm cube of carbon IV oxide
