very helpful! just wish you would have done a problem where n and t isn't given and there are more than 1 temperature, or something similar. having trouble with it. BUT U ARE SOOOOO AWESOME! saving me this semester for sure
I don't understand people complaining about the speed. Stop, take notes, and continue. It's not that difficult. Also thank you much for the videos. They are tremendously helpful.
This video helped me understand what I couldn't remember from last semester reading my book or be in lecture class in just one pass of the video I really like her teach methods. Thanks a lot to the uploader really useful stuff.
This isn't limited to a chem class, I learned about this in my Astronomy class, concerning the creation of starts as well as how the Ideal Gas Law relates to the kinetic theory of matter.
It's actually P1V1/n1T1 = P2V2/n2T2 = k, where k is the constant of proportionality. Therefore P1V1=kn1T1. P1V1/n1T1 is a constant, therefore for ANY gas mixture, PV/nT equals the same constant. The constant has been experimentally determined to be 8.31 J/K/mol, represented by R. Therefore PV/nT = R. Therefore PV=nRT.
this pace is good! you don't know how many videos I've watched where the dude talks WAY TOO slowly and i have to speed up because I already know what he's going to say before he says it.
Awesome video, helped a lot. I appreciate how you keep it moving through your videos, allows me to get what I need, so I can start the work I need to get done.
That will work, but there is a better option. You can see full transcript here - www.brightstorm.com/science/chemistry/kinetic-molecular-theory/ideal-gas-law/
Is it possible to measure air flow rates in Nm3/h using the Gay Lussac's law? Well I tried to differentiate PV=nRT, assuming iso thermal/molar conditions. However I simply can't get the normalised rates as being measured.
Actually, the real value for the constant R is 8.3144621 or 8.314473915 when dealing with kPa. Either way she is still right and YOU are wrong since your calculation is based of on the ROUNDED values of kPa(101.325), temperature in Kelvin(273.15), and molar volume(22.414).
I like how she talks fast like that, so we have to try a little bit more to keep up with her speed, that way we dont fall asleep (or maybe thats just how my brain works). Most of my science teachers talk very slowly thinking it would be easier for us to understand, but most of the time i fall asleep half way through their lectures because they're so boring.
TheLindsayNguyen Many students love the way she talks - very fast. In case you don't fully understand what she says, you can see transcript of the video on Brightstorm site. www.brightstorm.com/science/chemistry/kinetic-molecular-theory/ideal-gas-law/
yeahh...finally i found u miss...i don't have any problem about the speed at all...u helped me a lot..if there are lot more examples would be better..!
me the one who is here after approximately eleven years after uploading this video !!! wow ...sounds funny to me though !!...your video helped me a lot to understand the concept
Couldn't you start with ideal first, then do some problems, and depending on the problem use those numbers, and you can assume what they didn't give you is constant, and therefore end up getting things like the other gas laws, p1v1/t1=p2v2/t2, I don't know I still prefer to start with the ideal and getting to the equation that the problem requires, helps me understand everything better.
She knows her stuff and I have learned from her on the easier formulas but im always rewinding her videos because she talks way too fast for such a complicated subject.
I like your Videos they really hopeful, but shes really speak too fast, i do understand her! For the first time i understand fast speech. Just a little bit slow be all good. I like how she teachers really good.
The middle R solution on the board about Kpa is wrong... that calculation is actually 8.311794872=R, which rounds to R=8.312. You may be okay with the being 2 thousandths off, but smaller mistakes have cost lives. shame
haha you were wrong writing down the atmospheric pressure, its actually 5.15! since the decimals are: 5.144499802atm so if you round that up you get 5.15atm! sorry dear, i'm just way ahead of you. ;)
g/mm said gram per molar mass! First time I hear this terminology. Why not stick to what every textbook uses: mass over atomic mass (M_A or molar mass). No wonder people are disgusted with chemistry and physics. It's a lot simpler than this. The first example is a clueless arithmetic application. The whole thing lacks chemistry and physics: simply a rewrite of an inverse function in a P-V diagram! without this much mathematical insight either.

Thanks this helped me. My teacher spends and hour teaching this and you taught me in 5 mins
I like how she talks fast! She makes it faster and less boring. :)

Your method is shorter and less confusing than my method!! :O thanks for showing that method!!!!
Awesome video, helped a lot. I appreciate how you keep it moving through your videos, allows me to get what I need, so I can start the work I need to get done.
Thanks. We're glad to help.
Love your videos -- thanks so much. You make things very clear and easy to understand, more so than my teacher!
Infinite thanks for these videos!!!!!
Thanks for making these videos! It helps me to further understand my teacher's explanations! :)
Thanks my best teacher ever
thnx its really good to get chem lec and u done it very well you save my life thnx once agin
Great teaching!! Pause it if need to...Thanks
I really enjoyed the explanation, but the pace was very difficult. The pace she uses when she's copying information on the board works really well.
Pretty decent explanation... keep up the good work
Learned 2 weeks of school in 8 minutes and 44 seconds.
great job brightstorm i like it.. most
+biswaranjan nayak Thank you!
You don't know that you helped me a lot! Thank you very much.
R, the universal gas law constant, is always equal to .0821. It's the R in PV=nRT.
turn on captions. I promise it'll be worth it
That will work, but there is a better option. You can see full transcript here - www.brightstorm.com/science/chemistry/kinetic-molecular-theory/ideal-gas-law/
perfectionalist!!!!! cannot being described maan you are out of the world briiliant :)))))))))))
best chemistry teacher
explanation style and voice also very good.
Thanks!
Is it possible to measure air flow rates in Nm3/h using the Gay Lussac's law? Well I tried to differentiate PV=nRT, assuming iso thermal/molar conditions. However I simply can't get the normalised rates as being measured.
really good pace on this video, some of the others are a little quick
your video helped so much !!!!
this is so helpful oh my god thank you!
very helpful! Thank you!!
where did she get the .0821 from?
captions are epic, turn them on and get ready for a good laugh
Thank you so much, this definitely helped
Actually, the real value for the constant R is 8.3144621 or 8.314473915 when dealing with kPa. Either way she is still right and YOU are wrong since your calculation is based of on the ROUNDED values of kPa(101.325), temperature in Kelvin(273.15), and molar volume(22.414).
you can use the capital M instead of using mm to represent molar mass
I have a chemistry exam as soon as this video finishes.

You are such talented, I have been using your video from my high school to college. Simply the best.
Lady is youtube charging you by the second?
Calm down; why the rush?
what is the Value of R in Bar?
Some people use their left hand to do things instead of their right. It's called being left handed.
I've always used 8.314 J/K/mol as my value for R.
Come to my school and replace my chemistry teacher so I can learn things
Couldn't you start with ideal first, then do some problems, and depending on the problem use those numbers, and you can assume what they didn't give you is constant, and therefore end up getting things like the other gas laws, p1v1/t1=p2v2/t2, I don't know I still prefer to start with the ideal and getting to the equation that the problem requires, helps me understand everything better.
I dont understand how to get the density part...
why not write R= 0.0821 atm.L.K^(-1) like this? We would then know which units we use.
I thought the ideal gas law is PV=nRT?
she's either really nervous or hopped up on caffeine.
She knows her stuff and I have learned from her on the easier formulas but im always rewinding her videos because she talks way too fast for such a complicated subject.
khanacadamy is good, this lady is very good!
Thanks its helps............
I like your Videos they really hopeful, but shes really speak too fast, i do understand her! For the first time i understand fast speech. Just a little bit slow be all good. I like how she teachers really good.
i actually understand this crap now, thank you fast talking lady
30 k a year in college education and I have to watch these videos to learn better :/ ugh fml
my chemistry doesn't use moles. What do i do then
lol turn on the captions and have a good laugh
VaNiiLaBaBii hahahaha that was a good break from studying
3:46?
The middle R solution on the board about Kpa is wrong... that calculation is actually 8.311794872=R, which rounds to R=8.312. You may be okay with the being 2 thousandths off, but smaller mistakes have cost lives. shame
NICE PAIR
dude thats all i could think about the whole time. glad to see someone on the same page.
Feels like you talk fast. Breaking your words, slowing down a bit would be nice. Thanks for this video.
Yes, I know I can pause...
haha you were wrong writing down the atmospheric pressure, its actually 5.15! since the decimals are: 5.144499802atm so if you round that up you get 5.15atm! sorry dear, i'm just way ahead of you. ;)
I just got lost on the second part...lol
thumps up if your taking AP chemistry....
Umm...no. 5.144 rounded is still 5.14, not 5.15.
Nice videos! I love how she talks very fast.. its hard to pay attention to other videos when they take FOREVER to get the the point
haha, lol i just realised that, wow... fail troll. sorry for bothering this awesome lecture :P
@el22romantico oh and its r thats not given, not t lol
no worries the "fap" is a compliment
what the fuck kind of chemistry class doesn't use moles?
it also makes it harder to follow.
Play at half the speed
+TheChosenOne she sounds drunk AF. thank you for that.
make that 6...Unemployment rate is going up :)
writing with left hand
how the fuck berries did you get .0821?
Ya well that really isnt an option
this is painful to watch, it feels as if she's in panic the entire time
we do pressurenin Pa or Pascals......confused.com
Awesome great.>.>
I like your videos, but you speak very fast.
Might I suggest pausing the video periodically to take in the information better. lol I like her speed #Preference No hate, have a great day!
Compare her with other instructors she is a fast speaking lady. :) Have a nie day too!
pause the video then!
g/mm said gram per molar mass! First time I hear this terminology. Why not stick to what every textbook uses: mass over atomic mass (M_A or molar mass).

You can't be older than 14.
ya, still dont get it.
same thing.
Holy crap! If she is going to write that much, then the camera needs to zoom in or something! I can't read it!
U r rock madam ilove
Accurate information but you speak way too fast as sandra93886 said.
please slow down!
finding density is not fun
Why do they um um keep like umm using her for their like mols gram, ummm I mean videos?
PVNRT? Pervert more like!
@2010hotchick take a real chem class
you are fast..
constant units!!!!!!!! u might have learnt bfore
too fast :P
your talking way too fast, otherwise this would be great.
i really want to marry you
