Phase Changes

To see all my Chemistry videos, check out
socratic.org/chemistry
What does a phase change look like at the molecular level? We'll look at the molecular structure in solid, liquid, and gas phases, and see how the kinetic energy of the particles changes. We'll talking about melting, vaporization, condensation, and freezing.

Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.

[@vnrdlc]

Tyler DeWitt what are the phases

[@soccercrazy792]

You do a very good job of clearly explaining the parts of a concept and not skipping any important pieces of a conceptual understanding. Thank you for sharing this video with us.

[@therafleming-wilson1237]

Tyler, just wanted to say, you are helping me understand chemistry. I thank you so so much for your videos!!!

[@ladykanrojiarmyblink1570]

Stages of matter is physics not chemistry.

[@mariaaxp0]

6 years later did u pass?

[@jarrodiboitet]

From one teacher to another, you are a genuinely good teacher.

[@julieanneo2786]

yes so good my teacher assigns it so she doesnt have to teach

[@user-xe6ww4rp9w]

My teacher is making our class watch this but now I’m understanding chemistry a lot better! Keep it up! =D

[@heysuplmao]

lol mine too

[@chunkzfn3111]

@MANUEL GOMEZ same !!

[@jennaw3845]

OMG same!

[@carsonmcdowell3888]

Same

[@kliffmorrow6663]

Mine too lmao

[@lynnejonahpomeleu7274]

First year in Uni - so lost in Chemistry but your videos saved me.Wish other people explain things like you do :) Thank you again

[@RYEANkindaAWESOME]

I have a chemistry exam and you help so much with reaffirming what I've read

[@chunkzfn3111]

Five years later I’m in your spot .

[@busybessie9390]

i love that you used a mosh pit as an example hahahaha

[@lestarrr2733]

Hey Tyler, Im currently taking Gen Chem for summer session. I just wanna say thank you for your awesome videos , they are helping me a lot more than what my prof does. I have an exam on monday and I'm glad i found ure channel

[@senormisterioso2]

How interesting that I search the internet for a video for my students and I find a presentation made a Mt. Greylock grad! Hope you're well, sir.

[@tdewitt451]

Mr. Chesbro! What a surprise! I hope things are going well at good old MGRHS.

[@senormisterioso2]

I hope they are too! I'm teaching in NJ. Or, should I say, "The Peoples' Republic of New Jersey."

[@isaacbeast1561]

Hey mr.Chesbro I’m your student

[@agutierrez342]

I’m a student too lol

[@willrickerman5392]

I'm a random person reading this comment

[@ac7plays152]

tyler ur teaching is amazing

[@ethanbatman6623]

Honestly man, thanks a lot for making these videos, without these I would be failing out of chemistry. It seems like sometimes I literrally just write down the subject of what we talk about in class then come home and watch you videos to get the subject

[@exe.m1dn1ght]

lovely explanation ! ! !

[@2MomsTravel]

Tyler’s videos are awesome!! My daughter was struggling to understand these science concepts and he makes them so relatable!! Bravo!!

[@christheblondie6136]

I never got to/did properly thank you back when i was taking Chemistry. I would just like to say were it not for you, I would have surely failed. Thank you so much for the help

[@legally.chelsea]

OMG, you are explaining this so well. Thank you!

[@psychedelicmermaid2]

An exceptional presentation. Wonderful graphical representation of molecules. This has helped so much. Great selection of videos. Thank you for putting up great content. Please keep them coming.

[@emmaetheridge8657]

Thank you so much for these videos!! They make things so much easier to understand!!

[@aishwaryaanand2139]

Hey Tyler sir, could you please make a video on boiling point, melting point/freezing point. 👍🏻👍🏻👍🏻👍🏻😊😊😊😊😊👍🏻👍🏻👍🏻👍🏻👍🏻 pls plz pls pls

[@frejaskelton7147]

Super useful and very informative! Thanks!

[@cecy86v]

Do you have anything on equilibrium expressions and ice tables?? Btw, I been watching your videos for my chem1 and 2 they have helped me so much!!! Thank you

[@gooddeedsleadto7499]

Hi Tyler: Could you please do a video on Iron Carbon Equilibrium diagram? Thanks

[@toyinbankole9308]

you are the BEST

[@dominoscustomersupport4373]

Tyler, you have helped me so much that I can't even describe it! Whenever I need help with chemistry or I feel like my teacher will teach it (most likely in a poor way) soon, I always go to your channel! I love your enthusiasm at teaching chemistry and I hope that you will lead others too!

[@chloefresk4002]

why does dominos customer support need chemistry help what are yall doing in that kitchen my guy 💀

[@colleenwindell]

Hey Tyler, I like your videos. I like the format you use and your analogies. I do have a suggestion or two. First, you say that you add or remove "heat": what you really should say is that you add or remove "Thermal Energy". Technical and a bit nick picky, I know, but there is a difference. Secondly, not sure if you know about PhET, but they have a great simulation that you could work into your video. The thing I really like about the simulation is that is shows exactly what happens to water as it freezes that demonstrates how/why water actually expands when it freezes. The particles arrangement is the key. It is a little different than the one you show. Here's the link if you're interested. phet.colorado.edu/en/simulation/states-of-matter

[@tdewitt451]

You're absolutely right. "Thermal Energy" is the correct term. But these videos are designed for the most basic learners, such as the middle schoolers that I teach. I made a conscious choice not to use "Thermal Energy," because I've found that jargon is one of the fastest ways to make kids hate science. "Heat" is something that students have real-world, previous experience with, so they can build mental models with the concept of heat. "Thermal energy" doesn't mean anything to a 12 year-old, so they can't immediately connect the concept to something they already know. You and I may disagree on this issue, and I respect your opinion, but for me, I'll always choose the quickly understandable, relatable explanation above the more obscure, 100% technically accurate one. At least when I'm teaching young learners. If you're interested, I did a TED Talk about this concept: you can find it on the TED.com website under my name.

[@JazminZenteno1]

Tyler DeWitt Colleen Windell even my chemistry professor at my university uses "heat" instead of "thermal energy"

[@sarahthomason586]

+Colleen Windell Check out Tyler's TED Talk - he discusses his methods for teaching science and the choices he makes with language to best facilitate his student's learning.

[@remachita0617]

Sarah Thomason agree Sarah

[@JC-xk8vh]

Sorry, I am not trolling anyone here, because I am just taking Chem II right now, but I am thankful for +Tyler DeWitt style of teaching. These videos are what help me grasp the concepts and help me pass my chem exams, instead of the actual instructor that is teaching the lesson and writing the exam. I have to say this is my favorite part, "If you're interested, I did a TED Talk about this concept: you can find it on the TED.com website under my name." "Under my name" LOL But in all honesty I see your point +Colleen Windell, I am assuming you don't want us to water down the subject, but instead raise to the occasion and understand it on a very technical level, but not all of us are trying to become Chem majors. P.S. I love the PhET simulation.

[@ABigYeti]

My teacher is forcing me but its awesome I’m understanding chemistry more!! Ty

[@mxngokiwi]

this made me understand my unit A LOT more better, thanks

[@devashishjoshi6027]

Hi tyler i really like the way you send videos and your style and explanations

[@viharkanara5236]

+devashish joshi yup you are right

[@monishatejani1326]

ur helping my child lern chemistary ............i thank you for that

[@eileencush8050]

Hi Tyler. I would like permission to use your video in my course. Is there an email I can use to request permission?

[@rasielkitomari6296]

nice illustration

[@user-jo5dr4hu9l]

the only person who helped me with chem😅

[@ladygj4564]

Need a cooling curve video

[@raphaelflores5249]

hi! you have helped me so much through the year. but right now i am studying for my S.A.T test, and on our study guide their are a bunch of formulas and what not. on it, it has something called NO phase change, we where taught this today, i dont have a great understanding to it. i am wondering if you can help? the formula for "no phase change" is : Q=m(triangleT)Cp ., please help i want to own this so i can do good. your videos help so much thank you.

[@wingus9121]

Thank you I am in school learning about phase changes thank you I’m likeing

[@MerrittJoujonRoche]

This guy has great hair

[@kingjames-fn8ib]

do chlorine atoms extracted from salt (bleach) condense back into a liquid or solid state .Or do they stay in the atmosphere forever?

[@Hannah-se4mh]

you could gently move the paper back and forth to make the molecules vibrate in the liquid state

[@suzanu10t30]

"So the process from liquid to gas is called.." Me : mosh pit

[@seanlaster901]

there is something attractive about this and idk why

[@avanikumar8371]

Sir can you please explain condensation in deep

[@Lolzwutz1]

Why not show the crystal lattice formation?

[@jacquelynspathies4524]

best and most helpful videos! great descriptions and a lot of patients when explaining concepts! thanks for your simple explanations(:

[@brookkhan5065]

hi sir just wanted to tell you that if you are moving from a gas to a solid is it called deposition and from solid to a gas is it called sublimation

[@nathanfs1158]

P.s 262,841 subs wow such an honor I'm just sure everyone wants to be u bro

[@MegaPruddy]

Magnificent! Thank you 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏

[@james77011]

nice video 😀😁

[@miakelly7058]

i like this video it is so good. solids and liquids and gas he is so good figuring what he thinks

[@JC-xk8vh]

I want to go to this concert and fly!!!

[@demonlord8398]

Would you mind explaining sublimation and deposition?

[@masalagravy6061]

i can try lol but im probably too late. Sublimation is when solid goes to vapor, and deposition is when vapor goes to solid. They are opposites of each other.

[@agutierrez342]

Tyler I need some clarification pls!

[@JakeMB]

Have to watch for school rip

[@averyyeah]

Same sucks ass

[@jamaicansistarobinson7587]

GOD BLESS YOU!

[@alimamyfofanah3533]

Good guy

[@JazminZenteno1]

I searched up "intermolecular forms" and this came out. Do they have anything to do with each other?

[@x5xbeh117]

THIS GUY. THIIIIS GUYYYY. moi best friend right now

[@theoschindler641]

Miss Schmitt is an amazing teacher. You should decently except

[@RajeshSingh-tt7jq]

U r amazing bt add some more important things like give reason

[@ParadigmFluxEmporium]

what about transitions with sublimation and deposition? and also the phse change with gas and plasma. can you explain that with your hardcore punker molecules?

[@raphaelflores5249]

oh and its under Calorimetric formulas, if it helps you a little more to understand what im asking.

[@ladykanrojiarmyblink1570]

Just in case some of you didn't know, the process of a solid phase going to a gas phase is sublimation. From gas to solid it is called re-sublimation.

[@temaarif4373]

thanksa alot dear Tyler

[@-Honeybee]

Isn't steam just liquid water in smaller droplets? I thought gases were invisible?

[@OctopusExodus]

My online science class is making me watch this

[@darklight-yo5fd]

I was waiting for the sublimation and desublimation. 😊😊😊

[@mohamedmessouak2582]

dark light deposition

[@pfq1606]

I have to watch this for school thanks for making me have even more homework

[@anja4rrzombl]

You are really good!!

[@Diqmantx]

What does analogy mean?

[@sebastians7346]

its like a comparison between something confusing and something people understand

Tyler you are the best!!!!! ... should say my life saver 🖒🖒😉

[@amberruiz9431]

F PORQUE YA NO SUBE VIDEOS Y NADIE ESTA VIENDO AHORA SOLO YO NADIE MAS :(

[@smirkovs120]

Heat is movement heat is frequency .with frequency you can make object melt

[@jennyhe5971]

You are the best!

[@xhhdbdhsb8192]

Isn't it boiling, not vaporization

[@LOL-kq2dd]

What about plasma?

I agree with samsaranuva

[@juncarlalvarado9777]

uhhmmmmm. sir , why do it's temperate stays the same even if, it changes from solid (ice) to liquid (water)?
