Intermolecular Forces

018 - Intermolecular Forces
In this video Paul Andersen explains how intermolecular forces differ from intramolecular forces. He then explains how differences in these forces account for different properties in solid, liquids and gases. Some of these properties include the boiling point, melting point, surface tension, capillary action and miscibility. Intermolecular forces between gas molecules creates variation from ideal gas law.

[@Bozemanscience1]

A new framework for the AP Physics class will be used next year. I will start working on physics videos after I finish the chemistry.

[@shosha1771]

Honestly I love you man
without your videos, I'd be lost in the world of science

[@Daniel-bd5ur]

shiz happenes bro )::: same here

[@domi4hart521]

Why don't you marry him then

[@scoutea]

same without Bozeman Science i would prob go insane :(

[@AhmedEkri]

I love your beginning music. LOL

[@FilzSkillz]

I didn't expect to learn much from online chemistry videos but I was surprised, you're videos are brilliant and you're a very good teacher. thank you

[@ishansharma9492]

I feel that you have explained it in the best way possible!
That was absolutely wonderful .
I would like to recommend other guys that this video is very good and is worth watching
Thank you Andreson !!

[@sarafinamcinnis9990]

One of the best videos I've seen! Thank you! I'm extremely grateful for the 100 I'm about to receive on my chem quiz tomorrow because of you!

[@ItsShaday]

You just know how to make me happy! I didn't know you did Chemistry topics too! Thank God for you sir!

[@kirstenbradley1094]

Hey, I am at uni and every week after biochemistry I am so confused, your video's are amazing and so helpful! Thanks!

[@akshitaalikesramen5721]

Thank you Mr. Anderson. That helped quite a bit! Ready to get a 100 on my chem test tomorrow

[@supb1437]

You are my science sherpa, Mr. Andersen.

[@agnesecannarozzi]

Ok , i'm italian and i don't understand english so well, but wow i've understood everything in your video, and you explain better than italian 😂 haha , bless youuuu!!!

[@matthewpolicarpio3399]

I really love your videos! I survived General Chemistry I with your help! Kudos!!

[@katep198]

THANK YOU, MR. ANDERSEN!!

[@AimanM]

Very well explained. Thank you Mr. Anderson.

[@akalo23]

I wish you could teach at my school...You make things sound so simple!

[@drmksu38]

Omg omg i can't imagine how wonderful your explanation 🤦🏻‍♀️♥️♥️♥️♥️♥️♥️😭😭😭😭

[@mickiemox]

Your presentations are very helpful... Im in grade 12 just beginning biochemistry and you've got everything to offer that helps me understand !! Thanks so much ! I wish youd be my teacher :o

[@janeroth9465]

Question: Which of this liquid (water, oil and rubbing alcohol) have the most similar intermolecular attractive forces and why?

[@bsebastian2467]

Very helpful!

[@MantisRay861]

THAT WAS HELPFUL!

[@EMDIVSofficial]

Boiling Point Can i have a question what is Entalphy of Vaporization?

[@doreenbaraka6478]

yes very very helpful
you are always helpful thank you very much
don't stop posting :)

[@R00567]

Pls do a physics series, you rock!!

[@mynameisjujo]

A molecule in definition means a combination of atoms that are covalently bonded, so it depends what the molecule is. For example, a methane molecule (CH4 - One carbon that shares its valence electrons with four hydrodens)

[@PresCalvinCoolidge]

@2:40 You said Hg did not go as high in the tube as water since Hg is not attracted to the tube but water is. But why is this so?

[@2ndintelligentWorld]

can somebody tell me why CH bond is considered nonpolar when the difference in electronegativity is larger than .3?

[@reneehaugen3042]

It's never just one C-H. It's usually CH3 or C-C-C with the H's around the outside of the C's and the electrons are distributed among all of the C's and H's. If you ever had a single C-H bond in an asymmetrical molecule, it might be polar, but it never happens that way.

[@AimanM]

Thanks. Definitely helpful.

[@ishmael4489]

Yes, that was helpful. Thank you.

[@jessicaluciafloresgonzalez4519]

This is a good video. You are better than my teacher

[@Mabeylater293]

IntrAmolecular forces go A STEP FURTER and are the forces within the molecule. Just a trick I use to help remember. Hopefully it can help some else too.

[@georgelouis6515]

@3:30 if it's true what you say then how come we don't use Ethanol to spin turbines?!?!??!?!?!?!

[@brandoncazares8452]

This is helpful

[@muhammadmonzurul4903]

Thank you very much sir, this video was really really helpful. ^_^ (y)

[@brendanco8741]

OMG THIS VIDEO IS SOOOO EPIC CAN YOU DO A COLAB WITH DECENT FC plz i cant wait plz MR Bozeman Science man

[@sonavia87]

amazinggg!!

[@kaushikgohil5458]

best best best video

[@Shellperson]

Its Z=(PV)/(nRT). You left n for the compression factor. Overall though the video is good. :)

[@thaliansdown]

good video☺

[@camb8509]

thats the truth Gibby.

[@AlexPrimes]

watching from Philippines

[@jayathramahadurage]

What i think now is what the hell was my teacher teaching me all those days......zzz.sooo greek but now its like cheese

[@jennayoo4701]

TW to any of y'all who have trypophobia and this goes for every single one of these AP Chem Bozeman vids

[@AustinsAwesomeAdventures]

I like this 👍

[@gamerdude1246]

I fucking love you
My teacher is so bad...

[@pranavsood2058]

Anyone else thought that was a donut at the start? lol!

[@sciencenerd7639]

cool

[@joshgibson5888]

Stroke

[@njb6858]

careful - capillarity does not explain how water moves up a tree!

[@bee-wq9iu]

it doesn't?

[@julioservantes8242]

Water is not moving up in a tree because of capillary action.....

[@jamesguerra3885]

No! from fellow creatures

[@exiuss26]

ok he lost me....

[@armonmobasher5822]

hell no

[@fightbreastcancerwot7073]

Stick to Biology. Chemistry isn't your thing.

[@efegelibolu]

stfu

[@rebeccawilson-br3ip]

Pls do a physics series, you rock!!
