Find the Vapour Pressure (Clausius-Clapeyron Equation)

[@kristennoyes2188]

Even 10 years later, you're still saving chemistry grades left and right. This is God's work. Keep it up man, thank you so much.

[@chemistNATE]

LOVE IT. Ask me anything you want, any time. This invitation is for EVERYONE.

[@Thees5437]

12 YEARS LATERRRR :)))) Thanks alottt

[@ananyakatiyar3275]

woah this video is literally 11 years old and still a great help! thank you

[@lemonz1769]

My professor glazed over this and never solved an equation and my book doesn't even discuss this. For the life of me I couldn't remember how to undo the ln(x) and every other online resource just says to undo it without explaining how. Thank you, thank you, thank you!!!!!

[@thenotoriussartorius2405]

I never thought I would smile or laugh while studying for a Chemistry final. Thanks, needed that.

[@The5partacu5]

I've learned more from you than my Gen Chem professors, I swear. Keep on doing God's work man.

[@Palomino0813]

Thank you for being thorough! My textbook and every other website I looked at for the Clausius-Clapeyron equation assumed I knew how to undo ln and didn't go over it, and I was getting pretty frustrated. You made this equation easy for me to understand and made me laugh in the process. You've earned a new subscriber!

[@jhmasoud]

Other than the fact that you saying lawn drives me freaking nuts I appreciate this incredibly helpful video.

[@TheVenusRising]

THANK YOU!! I saw other videos but you are the only one who explained how to do away with the "ln". Other people were going right to the answer....so frustrating. Thank you thank you thank you.

[@UneasyTortoise]

i feel insulted yet educated after this :D

[@jessicahenry3352]

this video is so helpful when u have professors that are so not helpful. thank you for making this.

[@ItsssQuade]

THANKS SO MUCH FOR THIS! I have a chem test tomorrow and I was struggling trying to figure out how to undo the ln. Thanks so much for your help! You're a godsend

[@ComradeDispenser]

I always love when some random youtube video I found by googling a subject teaches me more about chemistry in five minutes than my professor does in fifty.

[@HellboyMPG]

Your an absolute legend of a chemistry tutor!

[@abduluddin5645]

haha ur pretty funny, first with the trust me on the kelvin cancelation then the suck it up on ln part, i laufed

[@mharth6594]

+Abdul Uddin I've been told to suck it up in football but I've never been told to suck it up in academics. Love it. I'm still laughing!!

[@xxthemcrkidxx]

You my good sir are both a scholar and a gentleman.

[@Whats_noah_up_to]

Lmao at 3:11 "the kelvin...... Whatever (cancels it)"

[@ViceroyNikolai]

This is the most well-explained video on this topic I have found, outstanding, well done and thanks!

[@jayjason556]

wow...90 mins with my professor= 7 mins of you

[@ramos8468]

3:11 " I got kelvins, ugh, whatever.. just trust me on that " LMAO me too. I still learned more from you than my other professors.

[@maya-dp9td]

I have my college final tomorrow and you just saved me, thank you so much for actually teaching how to solve it.

[@joshrevels9713]

Bookmarked the site. I couldn't find a submission tab on the site. Nate, Here is a list of items for my next test. Solve Henry's Law problems, Solve Raout's Law problems, Calculate freezing point depression and/or boiling point elevation. Calculate the osmotic pressure, use osmotic pressure data to calculate molecular weight. Keep up the great work! I loved the video for Eutrophication. Hopefully you continue so that I can use you as a resource for my students.

[@asisababun7543]

Best Video on CC equation by steps

[@albionhustler9836]

Thank you for the explanation of Ln at the end. This is what was stumping me!!!

[@lovelyperson9]

Hahaha "I got Kelvin...on the bottom of my...whatever. The Kelvins cancel out, just trust me on that." XD He was on the right track! So funny, thank you for making this video entertaining.

[@chemistNATE]

Those are BASICALLY the same equation, because vapour pressure IS a type of equilibrium. This equation is just a simplified version, for one specific process.

[@TheWiteshark]

the lawn, undo the lawn and suck it up

[@Juani2392]

gracias desde Argentina, me sirvio para pasar el examen. Thanks, from argentina, it help me for pass the exam of chemestry

[@joshrevels9713]

Thank you, Nate! This was helpful. Hope to see more videos of physical chemistry content by you. It'll help me through this semester if so.

[@chikoflake]

You are a life saver bro! There is no way I can thank you enough dude, I've always disliked chemistry because I've had very iffy teachers that just made it very confusing, but you explained it in a way that gets to the point without the confusion idk. either way you rock lol is that offer about test topics still valid?!?!?!?!

[@karinachavez9926]

You made this so easy for me to understand now! THANK YOU, I WISH I HAD DISCOVERED THIS EARLIER IN THE SEMESTER

[@ayowhogotyousmilin8691]

damn this video helped me at 1:30 am on a random school night even after 10 years

[@1887r]

Sir , you've saved my whole life , I had A serious problem with The Ln thing and forget about e 😅 .. thanks a lot

[@kevluv93]

Dude, THANK YOU!!!! This was so helpful you have no idea!

[@Scarecrow545]

For anyone wondering, the Kelvins cancel out because the one on the left was in the denominator of the denominator, which basically means it would go back up to the numerator.

[@natestewart8059]

Thanks, +ChemistNate! This made much more sense than the LiveScribe I was given by my instructor. I couldn't figure out how to address the ln portion to make it go away. And the T2-T1 parts on my calculator didn't work until I saw how you did it. Thanks for the helpful videos!

[@ChlorophylliaKZ]

Awesome explanation. Answered all my questions as I was working through this equation. and made me laugh! Looks like you posted this a while ago, but hey, thanks very much :)

[@dariomaidana9858]

From Argentina, Thank you!!

[@dnehl]

Your videos always put a smile on my face!

[@hisamazingg]

Thank you!! This really helped me understand my gen chem 2 homework!

[@chemistNATE]

If it's P2/P1 then you'll have a negative in front of delta(H)(vap). They're the same equation, just written differently.

[@MeowFacegmailcom]

omg thanks I was just going back and forth trying to figure out why two formulas had the same name

[@pobrien130]

Thank you so much you're such a huge help with all of my chem!!!

[@joudivilar]

You are amazing, your video was a great help, thank you for uploading it!!!

[@eatjinarmy3469]

You just saved my life dude!

[@javiendsnow]

chemistNATE.... YOU ARE a live saver buddy!

[@CODTALES-KILLSTREAKS]

This equation can also be used to calculate the vapour pressure of a substance inside of a vacuum. I did this also to predict the air density at altitude. Which turned out to be very close, obviously with the make up of the atmosphere it was a challenge but it’s pretty close.

[@runaraytrain8801]

I feel so educated, as well as attacked! 😂👍🏾

[@melvinvasquez8518]

Kelvins cancel out because everything in that parenthesis is one quantity; i.e. at end of the day it's one K not two.

[@mathiastolugu300]

Thanks for the example. Can you make a video about How the Clausius Clopeyron equation is derived?

[@xXInfernalWerewolfXx]

Loved the vid. great explanation, thanks!!!

[@YesNoMaybeSometimes]

6:13 to 6:20 best part of the video haha love ya man

[@xxLincixx]

Lol I love your method of teaching.

[@mohamednabil3353]

your way of explaining is really funny but it works (Y)

[@fnagum]

thank you sir. hope i can see more problem solving in your video. i have a subject right now physical chemistry and its not easy for me to understand only one example. thank you so much this will help me to pass my subject. love it.. we are using physical chemistry book by Moron and Lando.

[@fleurnoir98]

Thank you soooO much. This video has helped me ALOT!!!!!

[@chemistNATE]

@jalcazz If anyone laughs while doing chemistry, that's the best news ever. Thanks.

[@bqs175]

Edit: a video on Antoine's equation would be fantastic if you could make one!

[@jlee1131]

Thanks for the video, helped me understand it better :)

[@jennylopez1495]

This was very helpful!

[@saurabh9978]

nice... easy and simple..!! thanks very much

[@SmellyUnfortunate007]

Video: Tutor shows how the Clausius-Clpeyron Equation works with the end: "suck it up!". Me: Laughs unexpectedly after finishing Calc. 2.

[@viper8815]

Thanks for doing this clearly!!

[@ryan80166]

Thanks man you made this EASYYYYYYYYYY!

[@morenokevin94]

Thanks man well explained!!

[@budlight1835]

agreed kind of stupid thing to say but in fact they cancel because in the expression dH/ 8.314J/mol*K where mol*K are the denominator of the denominator, therefore, the K in the denominator of (1/298K - 1/373K)becomes what we could refer as the numerator and thats why they cancel. also is the same reason why moles of the dHvap cancel with the mole of the R constant

[@Andr295]

1:54... He's gonna call the pressure his first temperature... Lol... What the heck, let's call the our first temperature our first pressure :P This guys is funny. Great video, btw! It helped me a lot :)

[@VideoSouls]

you just saved me. thanks!

[@XxAutumn4xX]

PLEASE POST AN EXAMPLE ON HOW TO FIND TEMPERATURE #DESPERATE

[@rimsharana2782]

can you add things on your channel dealing with physical chemistry please? you are a great teacher!

[@chemistNATE]

I take requests! Facebook ChemistNATE or reply here !

[@chemistNATE]

A negative could be absorbed to do that too.

[@asdafasable]

Van hoff is again for one procces. right? i think you use the equation it fits with your data given . If you have pressured given you use clausius-clapeyron and if u have Kp you use van hoff . right?

[@mattjelani]

Thank you man! You rock!

[@melftheelf]

thank mr nate

[@asdafasable]

Why Van hoff is exactly the same except of P2/P1 change for Ln(K2/K1)??? when we use that and when we use van hoff?? thanks

[@musikmachine4]

very helpful, thank you!

[@RougeSamurai77]

Thanks a lot!

[@jeepgurl1379]

Okay, it works. I love it!

[@XxJRHxXREDX]

I'm pretty sure it's "ln(P2/P1)" not, "ln(P1/P2)"

[@BlueBabyAkaAj]

You can write the equation either way. Long as your pressure and temperature correspond. So it can be ln(P2/P1) but your temp will be (1/T1-1/T2) OR ln(P1/P2) WITH (1/T2-1/T1). Hope that makes sense.

[@chemistNATE]

CallMe_ShanLee ^^ She's right. Also, you can flip the P1/P2 in the ln by adding/taking away the NEGATIVE on the other side of the equation. Yay math

[@mylobage]

Was gonna say the same thing. Also he forgot the delta an needs a negative - in front.

[@crywolfx6176]

i think the negative goes away when he flips the p1/p2?

[@tzheng1tube]

you are right

[@depturreptic3512]

Thank you alot am contented sir

[@inneralpha]

Will this give you the vapor pressure at equilibrium? if you have a bowl of liquid water in a sealed container with ambient room temperature which was sealed after exposure to open air for a long time, you can't expect the water to reach 3.64kPa right away. There must be some sort of natural response. Is there a way to figure that out?

[@itswhoisme]

شدعي عليك امام🙏

[@m35926]

The kelvins cancel because kelvins in your R constant are the denominator of a denominator which makes them a numerator and then the other kelvins are in the denominator.

[@Phabine]

LOL 6:13 that's how I felt after this video! thank you!

[@prinzecesartonares9332]

is there a universal entropy of water for me to use to calculate the pressure of water at different temperature ?

[@DarknessLPs]

I was half expecting a "fuck yeah" somewhere at the end

[@mpumiem1205]

How do I calculate the 2nd Temperature instead?

[@Arca02011]

lol youre very entertaining, gonna sub

[@LiViNLiFEKRaZii]

So would that change it to (1/T1 - 1/T2) ?

[@sandradlugo]

thank you, god bless you :)

[@Paperclip718]

john malkovich, is that you?

[@JanetLedesma26]

Muchas gracias!me ayudo muchisimo

[@MohammadZavedSiddiqui]

I think R used here should be Ru/MW Ru=Universal Gas Constant MW =Molecular Weight

[@jelloboquiren8530]

Thank you Sir

[@fazoonotila1302]

Very good ^^

[@HS-jg8ti]

Why did you remove the negative sign from in front of delta H/R?

[@michellecullen2889]

If you get a question: 'At what temperature do solid and liquid co2 co-exist?' and your given vapor pressure of solid co2 is ln(p/p^0)=-(3,118.5/T) +16.003 and liquid co2 is ln(p/p^0)=-(2,044.9/T) +11.050 how do ya do that question??? :)

[@mariaorsic9763]

I think its P2/P1 and not P1/P2!! Thank you anyway!

[@chemistNATE]

In a nutshell, yes.

[@MS-vx4ff]

If John Malkovich taught chemistry ...j/k j/k awesome video lol

[@TrumpPlays]

what mode should my calculator be in ... after I do e^3.32721 I get 2.786022376e1

[@Kawther.collection]

Thnx a lot
