Literally I understand these concepts with ease while Khan sir teaches. My school teachers diffusion rate of concepts is 1.17 times slower than sal sir.
i wish if you can make renal system videos soon ..my final exam in 2 month time ...THANX A LOT! I HAVE GREAT RESPECT FOR YOU ..SAY SALAM TO SALMAN FOR ME IF YOU MEET HIM
I guess something is wrong in this explanation. If the nummber of the molecules in the pot are the same (moles of O2=moles of CO2), then you can put directly the MW in order to compare them. But consider for example you have one molecule CO2 and 1000 molecules O2. In this case whether you have to consider the relative pressure or the mol numbers to have a correct equation. For example: n1.MW1.V1 ^2=n2.MW2.V2^2 It is not like this?
how can you dectect something if you dont know what it is? you couldnt tell me the difference between a house and a church if you had never seen either
Guys any help? The density of a gas of relative molecular mass 28 at a certain temperature is 0.90 kgm-3. The root mean square speed of the gas molecules at that temperature is 602 ms-1. Assuming that the rate of diffusion of a gas is inversely proportional to the square root of its density, calculate the density of the gas standard temperature and pressure if its root mean square speed at is 490 ms-1.
For Hydrogen would I use 1 or 2 for its molar mass? I don't know what to use because my chemistry teacher said hydrogen was a diatomic element but I don't know if it's applicable to this situation.
Hydrogen exists as H2, so it would be 2g/mol. It's the mass of the gas, not the element[s] the gas is named after; you have to reference the chemical formula of the gas.
So basically after he writes RateO = √44/32 he simply gets the square root of both then what he does ? How he gets the answer simply of 1.17 how? And he multiples with rateC but for now we know we don't have rateC yet Confusing someone help.
Yo rate c indiacates the rate of diffuson of carbon atoms. And he got the answer simply with the calcultor , I hope your doubt got solved after a couple of years
Do you know what the alien 👽 would say? Well I know 😏 It would say, Mmmm! what a mouth watering smell 😋! We never cooked this kind of delicious gases in our planet. I want more. What else would you expect from him to say? LET ME KNOW.
If you didn't understand this, just rewind to 8:49, and listen up.
Literally I understand these concepts with ease while Khan sir teaches. My school teachers diffusion rate of concepts is 1.17 times slower than sal sir.
What? Literally what can I do to reach this level of understanding? This is just an amazing explanation. Thank you and God bless you.
True , I'm in 9th standard and Ive heard I need to learn this for JSTSE exam . He explained it really well
I've yet to see/hear a better, more concise explanation of Graham's Law. Thank you so much, man.
The point at which my google search results for doubts end...is where khan academy videos start.
No words to praise u sir....u have really hit the nail on the head.....!!!
your example was awesome!thank you for this good explanation.
This alien friend is from 2020 earth.
Absolutely gr8!
thanks man best use of 8.57 minutes of my life
thank you so much now I understand the concept of graham's law.
LOVE this explanation. Thank you.
Are you alive if youre alive like my comment
Explains 100% better than my chem honors teacher
Your teaching is very interesting. Practically explanation is very nice.
God bless your soul,Sir.
You too!
Thank you!
You've got yourself a new subscriber
Do you know who the new subscriber ks
@@devadharsan7721 That's either a joke or ur stupid lmao
It's good so many sciences use this law.

You just saved a life 🥺 thank you🤲🏾

It is not like this?
Thanks
Nice explanation 👌👍👍😄
It’s great
Good video
thank you so much, I love you for this
thanks u gave me a new formulaae
Ok 👌👌👌good
does it depend on the number of moles of gas?
how can the alien tell you which one he smells first if he never smelled any of the gases before
Lol ...he has a special nose and can detect the gas... As said in the video
how can you dectect something if you dont know what it is? you couldnt tell me the difference between a house and a church if you had never seen either
Respawn Master u r right same question emerged in me also!!😂😂

hiiii
can you tell me please what ddi you use to make this video what is that tool you use to appear on screen like a black board???
He used carbon atoms as they have more diffuson rates and black colour.
idea is nice to explain Gharam's law
in tamil graham means plane
So basically after he writes RateO = √44/32 he simply gets the square root of both then what he does ? How he gets the answer simply of 1.17 how? And he multiples with rateC but for now we know we don't have rateC yet
Confusing someone help.

Explain defusion too
Can anyone tell me why he did the rate of oxygen and not carbon dioxide first?
what is kinetic energy? please explain.
you shouldnt be here
A cumbersome metaphor, but I grasp the concept and the goofy video will help me remember it.
This is so confusing and convoluted.
5:23
Why does carbon dioxide goes on top and not bottom ?
+Andrew Lam Because of providing energy to molecules, so they are moving arbitrarily. Sometime carbon dioxide molecules can be on top and vice versa.
i like looking at his handwriting lmao
ITS NOT 1.17 it’s 1.2 :))
How do I know which gas is rate 1 and which gas is rate 2 ? Or does it even matter ?
+Andrew Lam He said rate 1 for oxi and rate 2 for carbon.
it doesn’t matter so long as you are consistent
He talks english?
He wouldn't have any problem cooking your pot haha
Telepathy.
Are you alive?
This is untrue in the human body. Co2 is faster.
Awful example
18 blue aliens disliked it 👽
You alive?
Do you know what the alien 👽 would say?
Well I know 😏
It would say, Mmmm! what a mouth watering smell 😋! We never cooked this kind of delicious gases in our planet. I want more.
What else would you expect from him to say?
LET ME KNOW.
thank you so much now I understand the concept of graham's law.
