Under the hood: The chemistry of cars - Cynthia Chubbuck

[@scottseptember1992]

This is the most bad-ass TED-Ed video I've ever seen in my life. This seriously put what I learned in chemistry into perspective. This is like one of the few TED videos in which I actually learn something new in. I wish I could like this video 1000 times. AMAZING JOB!

[@singleturbosupra7951]

Ikr. I had heard nothing of this either. It was mindblowing

[@memo6032]

And physics also! I took specific heat capacity in phyiscs.

[@AB-tt6qs]

So it's been 6 years. Have u created the solution??

[@Breathingdeeper]

"We can create our own solution!" that was beautifully said ms. Cynthia

[@josephm.6453]

Puns are great.

[@No_Englaisy]

Why did I not get it?

[@Breathingdeeper]

Cuz you haven't passed basic chemistry?

[@No_Englaisy]

Kyle D Sheesh, ok sorry. You win grand master of puns

[@Breathingdeeper]

SHANE HOWL'S dude don't cry about it lol. Solution was the pun

[@UWBadgers10]

very educational video. I'm always impressed by how they combine many aspects of chemistry together in one video.

[@BreezyInterwebs]

Dat ending pun though.

[@RinoaL]

you guys missed the chance to talk about how the chemistry in the battery releases stored electricity to start the engine. you don't start the engine by putting gas into it, you have to turn it over first. and yes there are some engines from the 1920s that start from just the fuel but its very rare.

[@timlang3852]

Rinoa Super-Genius Has

[@nemodot]

I love these Ted ed videos. They are extremely Easy to understand, the ideas are very well explained and portrayed. Good job guys.

[@diytryin]

We love cars! Great video, TED-Ed!

[@TimoIvvie]

How dose this only have 200,000 views? THIS IS SWEET!

[@leaf4267]

One of the best voices on TED-Ed.

[@anilparmar5881]

oh!!! now I understood why Chemistry teacher taught Relative Lowering of Vapour pressure in school.

[@deltapag3247]

Great video, shows how important a cooling system is for an ICE vehicle. One small thing was a bit annoying. Hot coolant returns to the radiator from the top and cooled coolant returns to the engine from the bottom. Also another little tid bit of info, the energy that a conventional fan consumes just so you don't overheat is approx 40 gallons of gas per year.

[@disrael2101]

Keep posting such informative eli5 explanations about practical life products

[@mattyonsurvey]

This video looks like it was done in the 1990s ♨️

[@waengwang5313]

on purposes

[@Timyz250]

I would have thought that the natural convection current should go in the other direction? Feel free to correct me if I am wrong here...

[@nakulpatel5095]

Why KZbin took 5 yrs to recommend me this awesome video,,

[@Danieleghedix]

very well explained!

[@JtrainMedia]

Pretty awesome video!

[@joeshmoe781]

One thing not addressed here is that water is a much more efficient conductor of heat than a solution of water and anything else. The solution has to over come that inefficiency to be a better solution as well. Just getting the air out of a solution is a great help. Much less chance of bubbles forming in a closed system.

[@CesarPerez-pu2hy]

"But instead of searching all over the world for the perfect liquid to solve our problem, we can create our own solution." I see what you did there. =3

[@levnekov]

Where's the background music come from? Sounds like that song from Joel's Duwand dub.

[@xapemanx]

propylene glycol is more commonly used because of its lower toxicity.

[@strange_and_magnificent]

Love this vid! 👍🏻❤️👍🏻👍🏻

[@Fidgety_fugu]

What was the background music? It's awesome!

[@giancarlo_rc]

* That last pun deserves top credit *

[@profveshagen445]

Hello Ted Ed, i have a question ,if the cars that are in southern hemisphere that means the cars no need to the solution so can use water right?

[@STARPHROST]

what about cars in places with extreme winters?

[@brianwyters2150]

Water at a high pressure has a lower boiling point. This occurred when Peter Scripol tried to make a steam powered nerf blaster.

[@originalvintage]

love it!

[@moflyboyblanquito541]

Weird. So both water and ethylene glycol freeze at a colder temperatures Together than when they are separated. That’s so strange to me.

[@veronicamcghie5238]

Neat video but what was up with the grainy filter overlay?

[@BioBrain]

VFX overdose :D

[@trillboypaulo8258]

I love cars. :) I've always wanted to be a mechanic.

[@dickvanfreedman]

***** I too love cars, so I fucked one.

[@jvaldez97]

Nice pun at the end :D

[@shookones5]

Great Video!!!XD

[@AB-tt6qs]

Present Sir! Better late than never.

[@AphroditeTales]

Whish app used to make this video Please!!!

[@kevinb_45]

My kind of science!

[@mrskujo4359]

why a solution has a higher boiling point?

[@LlwtyDeer]

In brittan, we call the 'hood' a 'bonnet'

[@تاريخالرومان]

+8 Bit Maping UK All around the world, "Brittan" is called " Britain" .

[@hkayakh]

Got that adventure capitalist music going

[@mod.ts76]

That's my chemistry teacher :D

[@wingedwhale7371]

mine too :D

[@iwantmyfriescrispynotburnt3981]

this music makes me wanna watch Ren and Stimpy

[@GururajBN]

The narration could have been a little more leisurely. Sounded rather hurried. What kind of gases are produced when the petrol air mixture is ignited? Why petrol is the preferred fuel? How does mixture of ethanol petrol fare compared to petrol per se? These questions too should have been addressed.

[@kurtilein3]

yes, well, interesting, but where was the chemistry? liquids being heated and cooled and boiling and freezing.... thats all physics. the only chemistry in the video was the short mention of combustion at the beginning. thats the only chemical process in the video, and it was just mentioned.

[@JunSian1001]

It depends on how do you see "Chemistry" and "Physics". Do you heard about "Physical Chemistry" before? This branch of chemistry works a lot on physical properties of chemicals, such as specific heat, boiling and freezing points of chemical solutions. I think many college science students will take it in their first or second years.

[@kurtilein3]

Jun Sian Lee if there is a chemical reaction involved, its chemistry. physical chemistry is not chemistry if there are no chemical reactions involved. in physical chemistry, you can for example have a gas that has really weird physical properties, because there are 2 or 3 different gaseous substances inside it that react with one another and form an equilibrium under constant pressure and temperature. like for example NO2 and N2O4. N2O4 is diamagnetic and colorless, while NO2 is brown and not diamagnetic. now that is chemistry as well as physical chemistry. but the stuff in this video just isnt chemistry.

[@DOSTalks]

"Chemistry: the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances." Solution boiling point and cooling is all chemistry. Physics is more abstract and doesn't concern itself with individual chemicals and their properties, but the rules which govern all matter uniformly. Hence varying solutions and the properties of various chemicals i.e boiling and freezing point, is in fact chemistry

[@kurtilein3]

***** no, its physics, because in this video the properties of individual chemicals are of no concern, and there are no chemical reactions going on. phase transitions, freezing and boiling, and pressure changes is physics. thermodynamics is physics. thermal capacity is physics.

[@justineramos4353]

kurtilein3 you just never give up lol

[@duckiebee2831]

So around 1 car for every 7 people?

[@Mogley-cr6ip]

yeah none of that was really much to do with how cars work and the genius behind the engine itself. quite insightful about anti-freeze though.

[@andrewshen2005]

That solution pun thou. Ugggggg

[@davidgruen7423]

What is our “solution”???

[@davidgruen7423]

And who are “we”?

[@RNCHFND]

You should have used "fuel" for example instead of "gasoline"

[@lekvoljin7052]

I think the engine with spark plug make it easier to understand

[@arvindian]

''we can create our own solution'' :)

[@Alas_Earwaxx]

Well, how do we create our own solution?? Or was it a figure of speech??

[@KevinTherrien]

"Nothing is lost, nothing is created, everything is transformed." Antoine Lavoisier. 1 billion cars who produce heat... we don't have to go far to find out who is responsible of global warming. At the end of the video it says: .We have to find another solution..." I think isn't an other cooling system, but a solution to replace the conventional car like bicycles, solar planes, electric cars, etc.

[@kurrizzle]

Ha. We can create our own solution. That's pretty good.

[@charles88]

內燃機 水冷散熱

[@tldslw]

Cool

[@ethanchou4906]

do u mean hot?

[@Omidph12]

nice

[@StellariumSound]

COMMANDER CHUBBUCK

[@Patrick-cy2zh]

Say what agian?

[@2001bmwm3e46]

this is more thermodynamics than chemistry

[@dylanthavillain]

The title is very misleading

[@bambel4997]

This video only described how the engine is kept cool...

[@kamenidriss]

so many puns...

[@paulsunday7688]

Considering the title of the video, this video could have done better. You only focused on the cooling, when we know there is more happening in a car

[@gamiezion]

ugh, the way an engine works is possibly one off the most explained things. it's part off why i dislike cars in general. as a kid i just saw and read way the hell to much about this banal information.

[@gabegiancarlo3698]

The engine starts with an electronic motor

[@Joe-sr2pm]

cool

[@drgrad7807]

Turkish subtitle please..

[@pascalsys1371]

It's all good in the hood.

[@DOSTalks]

Liked the pun at the end there 10/10 would cringe again

[@wfgames6373]

At first, I thought a Kurzgesagt video was starting.

[@hectormontes7056]

We can make our own SOLUTION!

[@razwanjamal2616]

💐💐

[@aXimo]

And that's how one kills the Planet.

[@supcomFAN]

Dat yogscast music tho xD

[@Mogley-cr6ip]

lol first 30 seconds, wrong! that would be true if it wasn't for an ecu but i'f you're going to call it the chemistry of cars then you may want to look into cars post 2002.

[@WhoooLovesOrangeSoda]

Electric motors > Internal combustion engines

[@WhoooLovesOrangeSoda]

***** -They are much more efficient - A Tesla Model S gets 90 MPGe -They can be much smaller and produce much more power - Model S motor is the size of a watermelon -They are much quieter - A good thing for a family car to have -They don't pose a fire hazard - as opposed to the number flammable liquids in a conventional car -They do not leak -They do not pollute -100% torque 100% of the time -Doesn't waste energy - naturally pumps forward momentum back into the batteries -Allows for more interior room -Faster than an ICE with the same horsepower - no transmission necessary -MUCH less to go wrong - Model S maintenance: tires, wiper fluid when necessary and then wheel bearing at half a million miles. Would you like more reasons?

[@WhoooLovesOrangeSoda]

***** If you say MPGe is "idiotic and irrelevant" then you have no idea what it is. Im not even going to waste my time because you clearly have a bias.

[@WhoooLovesOrangeSoda]

***** It is simply the distance an electric car can go on the amount of power generated by a US gallon of gasoline. It is a standard unit of measurement for an electric car's efficiency judged by the EPA. Even if it did only get 75% of that 90 MPGe, that is 67.5 MPGe on a US gallon of fuel, better than anything else on the road. Battery technology 10 years from now will be very different. People are aware Li-Ion batteries explode and that is why there is a larger gauge of metal to protect the undersides of Tesla vehicles. That is also why people are working on different types of batteries as well. Give me some reasons why Internal Combustion engines are better than electric motors. Focus on the motors, not the fuel itself. That's what I was doing if you didnt notice.

[@roidroid]

WhoooLovesOrangeSoda Some modern li-ion batteries can't explode anymore, you can hammer a nail right through a LiFePO4 battery and it'll just smoke a bit, no explosion no flame. They're also incredibly fast to charge and discharge, and are thus already commonly used in vehicles. Not in the Tesla cars though.

[@WhoooLovesOrangeSoda]

roidroid Tesla has Li Ion batteries for the 160m and the 230m range packs. the 230 is just more of them. the 300 mile is their own type I believe only in the 85kw, P85 and and P85+ models which uses zinc, aluminum, magnesium, iron, lithium and vanadium as well as other metals. The patent for which is free to use as of last month along with all of their other patents.

[@Dontworryboutit247]

All of the scientific concepts mentioned in the video are grade 11 University chemistry Level.

[@nandoanalog]

fuck it, I use water

[@mattyonsurvey]

What?!

[@walkthelineable]

my head hurts

[@ChadWardenPS3]

This has nothing to do with cars. It's all about the anitfreeze you put in a car

[@utkua]

metric system at last

[@idontuploadjustwatch]

wow, fuel injectors, carbs only for me

[@3800S1]

+idontuploadjustwatch ewww carbies.

[@purdypebbles]

Good vid. But shame they got the engine-to-radiator hot and cold pipes the wrong way round. Still good vid though.

[@AgentSkillz]

Guys please don't come to my channel. Face it ur not mature enough. Its just too disturbing for you. You won't regret this decision! Please don't even think about it. You will regret it forever. If u choose to disobey dislike to stop this from getting all over youtube! Thank you! RATED D

[@tpespos]

Ha puns

[@prashantdidule]

a indian created the water engine

[@funkblack]

That voice is kinda annoying..She's like reading from a long script..Not like the others narrators.

[@KookueCachoo]

Doc. FunkBlack I disagree I like her voice.

[@davishatler1874]

Is she plugging her nose?

[@HumbuckerGuy]

If you make another video just go ahead and use a computer voice.

[@LMTF35]

F°

[@ashkanahmadi]

Great info thanks but PLEASE do NOT use her again. Her voice extremely nasal.

[@star_strafe3951]

Why does the narrator have a clothes pin on her nose?

[@MrRende321]

Punny TED-Ed.

[@takaditakadang]

So inefficient, hopefully this dinosaur of a technology will be obsolete in the next few decades and replaced with electricity
