Specific Heat, Heat of Fusion and Vaporization

[random3148]

Thank you so much! Now I won't fail my test!

[ledzeppelinrawks]

Oh my goodness I understand O.O

[0M3D1U6]

at about 3 minutes the narrator says "Fusion 100 o water" which is wrong. Heat of fusion is occurring at 0 oC

[SXSA51]

WOW, the way my teacher explained it was no where near as comprehendible as this.

[RAYz544]

THNX internet is the best tutor of the world :P

[jjjooorrrjjjooorrr]

Do you know everything!!!?? THANK YOU!!!!!!

[BorealNeal]

this is hard :(

[PaulRyan2k]

Wouldn't this be classed as Physics, not Chemistry?

[Sushiarushi]

@PaulRyan2k no its chemistry, it deals with the change in the specific heat of elements. We're learning about it now in AP chemistry.

[PaulRyan2k]

@Sushiarushi That's weird, because in my course it's in my Physics, not my Chemistry book. Oh well :P

[vvoops]

@Sushiarushi AP chemistry? Im learning this stuff in honors chemistry, does that mean AP is going to be a piece of pie?

[jityr2]

At the beginning he says "A  couple of videagoes". That's cute.

[surdana]

Why does the anion have no affect on the color of a flame in the flame test?

[codutic]

He mad a mistake about 8 minutes into the video. He multiply 335.55J by 200 g when it should be 333.55J by 200. So his told answer is off by 400J

[WerewolfSlayer91]

Man this guy has MASTER degree in EVERY F***** subject, with technical education.

[JunkYardBuild]

A 7:25 you put in a value for Hf of 335.55 when it should be 333.55, not that it makes that big a difference but it should be fixed ;)

[DeltaCJ]

it finally makes sense!  thank youuuuuu sir!

[falls0ft]

@Maishir Yes, the Celsius and the Kelvin scale are essentially the same, except 0K is -273.15*C so the kelvin scale starts at a lower point but the amount of heat you need to add to increase by 1*C or 1K is the same - (or for liquid water, 4J)

inb4 confusing

[FourEyedLadyOriginal]

Well done!

[AhWing89]

thanks for the info.

[slutiva]

see 00 to 00 ;28

[Hemouth]

easiest video so far.

[rocker247chick]

AMAZINGGGGGGGGGGGGGGGGGGGGGGGG­GG!!!!!!!!

[mondo1318]

I cannot thank you enough for all your videos. I have used them for Physiology, Chemistry, Microbiology, & Physics. Always so helpful, clear, short and sweet! You are awesome!

[singhsomesh99]

Good concept!

[MsMerox]

COOL VID..gr8 job in educatin ppl~

[TrickingCanada]

THANK YOU!!!! =)

[Violetavrie]

So... Kelvin and Celsius are interchangeable?

[Representt]

@Violetavrie

for specific heat yes

[MsMerox]

@Violetavrie

ya- 373 K = 100 degrees C

:)

[desidol22]

ahhh! Thanks so much! i finally understood this stuff :]

[Brelikath]

He messed up.. it's not 335.55, it was 333.55

[Billabong024]

aren't you supposed to go from 100 degree water to 100 degree vapor before you go from 100 degree vapor to 110 degree vapor?

LOL never mind.

[Billabong024]

aren't you supposed to go from 100 degree water to 100 degree vapor before you go from 100 degree vapor to 110 degree vapor?

[Ibahz]

@Billabong024 yes he screwed up

[moodles14]

Sal, my chemistry teacher has told us that the specific heat of liquid H2O is 4.186, while you have 4.178. Is there a significant difference between the two, or do both of them work well?

[caribbeansuntrue]

I notice you did not convert Grams to KG. so i'm afraid all the answers have to be divided by 1000. good video otherwise.

[bb33nnii]

god bless the youtube teachers

[gumdrops27]

U just helped me understand something that took a week for me to even get enough interest to try in school. Come to my school and be a chemestry teacher please. :)

[hishamudai3]

@gumdrops27

Its physics bro..! (A) :P

[gumdrops27]

@hishamudai3

Oh i guess i totally don't know what class i'm in. Maybe i'll let you choose them.

[roxychick800]

@hishamudai3 its chemistry too dipshit...

[u218064]

I knew it!! you had forgeten to make the calculation from 100degree water to 100degree vapor... I was starting to get confused, hahah

[karevkarev]

How can I have steam from the hot shower, if water is belove 100 degrees?

[SirMaarten314]

I have a question probably a stupid one but nevertheless here it is:

Once the ice is heated enough it turns into a liquid shouldn't we change metric system? after all aren't liquids expressed in Liters?

[ToastMasterGuy]

@SirMaarten314 No question is a stupid one. ;-)

You would not make this conversion because grams measures weight while mL an L measures volume, two completely different things. Also grams is metric already XP.

[apasionadagatinha]

That was really helpful!! Thank you so much! I was wondering if you could tell me why you didn't include the negative sign of -10*C in the first calculation you did?

[camjw12]

@apasionadagatinha cuz you suck!

[RsGhost1]

@apasionadagatinha Because it's the temperature change, 0 - - 10 = 10

[KingJulien234]

I love you xD. Everything is just so easy and logic when u are explaining, it's not even a challenge anymore LOL. thank you so much for uploading these videos

[sita1039]

thank you this helped me alot in chem class

[tangnatalaga]

So water vapor can be hotter than boiling water. Thnx

[1aliceinchains]

I just want to say thank you so much for your videos. I am a university student studying medicine and taking chem and physics. These are at a higher level than this, but having not taken these subjects even at high school level I was pretty much doomed to failure as I had no background to build on. Without these videos as basic building blocks to catch me up, I doubt if I'd have even passed. As it is I'm an A+ student with an A+ average in these subjects. Owe it all to you!

[MattS6993]

@1aliceinchains I'm doing the course this year :)

[Fungwabus117]

you are awesome these videos are logical and help me understand thanks bro

[tangnatalaga]

@Fungwabus117 This is actually classical physics. Extreme physics such as quantu mechanics defy logic making them very interesting.

[mercifuldarkness]

u r amazing

[SteroidsR4success]

Why am I still going to school if I learn more information and get a higher level of intuition from just a single video; just a single concept. Damn Sal you're only after one video just on concept and I feel enlightened, thank you.

[brownnpink14]

sixty seven thousand one one ten. haha

[msmoviemadness]

Problem... it's 333.55 not 335.55

[omogaju]

I believe it is 333.55 and I am not quoting Wikipedia

[Pootboot]

One thing has always bothered me Sal, would you find it interesting to comment on how people can superheat/supercool water so that it could be liquid at a very high/low temperature?

[doomkun]

I think what you're referring to is a bose einstein condensate.

[Pootboot]

I do not think that would make much sense, nor spark any fires of recognition in most people eyes :P.

Thus a video or even a comment explaining it would be amazing for most.
