Heating Curve and Cooling Curve of Water - Enthalpy of Fusion & Vaporization
ฝัง
- เผยแพร่เมื่อ 6 ส.ค. 2024
- This chemistry video tutorial provides a basic introduction into the heating curve of water and the cooling curve of water. As heat is added to water, the temperature increases which increases the kinetic energy of the molecules. At the freezing point of ice, adding heat will not change the temperature but will increase the potential energy of the molecules as ice melts to liquid water. The enthalpy of fusion is the energy required to melt 1 mole of ice. The enthalpy of vaporization is the energy required to boil 1 mole of water into steam. The slope of the lines is inversely related to the specific heat capacity of the substance. The heating curve represents an endothermic process and the cooling curve is an exothermic process.

wow i’m really about to fail this chemistry test
Yup you sure are
The thing is
No I’m in eSchool cuz of corona and I have to learn this all by myself:/
@@amruthaayyappan5927 oof same :(
Your not the only onee
You are amazing. Saving people’s GPA one video at a time.
Best teacher ever ,you have helpd me with my daily lesson. I greatly appreciate your effort. ❤❤
I wish I could pay you my tuition money instead of emptying my pockets at cal poly only to teach myself through your videos
dead ass, online lab, at cal poly, and we didn't even have a lab meeting. I'm dying here. Kinda shrug at us and went good luck.

Thank you so much my teacher did not explain this at all and this really helped
th-cam.com/video/o2kYyvxtAAQ/w-d-xo.html
th-cam.com/video/ivcwK6j1xZs/w-d-xo.html
Me too , I’m really concerned on how my school is hiring these fucking teachers
I’m watching this as I’m taking my finals for chem 😅
SAME LMAO
Same lamaw
ME TOO LMAOO
only 15 hours till my final!
Same😂
You deserve a big reward for these videos thank you thank you
Thanks! I grasped the main concept of it!!!!
I have reach the point that even if he's the one explaining it, I just can't understand this :
It's alright as long as your still a human
I thought I was the only one :') but your comment was like before 11 months ago so yes I am :')
@@okami4065 such a positive comment :')
@@sally0541 don't worry, I got you company.
@@sangchi8368 :((🤍
you make me cry tears of happiness
Thank you so much, Is it possible to give an example of how much heat is evolved in converting steam to ice?
th-cam.com/video/o2kYyvxtAAQ/w-d-xo.html
th-cam.com/video/ivcwK6j1xZs/w-d-xo.html
Yep you got all the numbers
(You need a specific temp for steam obviously)
great, time to fail my exam
same. I got my midterm in 2 hours :)
Yh dude
@@ellemao8586 how did you go?
@@olay4520 I can’t remember what I got on the midterm but I passed the class :D
@@ellemao8586 That’s great, what grade are you in now :0
Thank you, sir
Thanks dude
Your channel is really great, ❤❤
Thanks. I understand now
my teacher just explained this and i wasn’t listening so i’m watching this now ;)
Seriously-💀🔪
@@mArtoffical SAMEE
same
Wow this is really interesting
Big thanks
what are the factors influencing the slopes of each segment of the cooling curve and the length of horizontal segment

th-cam.com/video/ivcwK6j1xZs/w-d-xo.html
did you ever find an answer? i'm currenlty wondering about the same thing
Wow! chemistry u will kill me one day
I have an argument with a friend: I’m sitting on a terrace. It’s 40C and sweating. I climb on my bicycle (or motorbike) and go for a ride. He claims that as the temp is at 40, hence above body 37C, my body will gradually warm up, i.e. there is no cooling effect, actually the contrary resulting in even greater discomfort. I claim there is a cooling effect. If I’m right, is there a point of temp where this effect reverses (sauna effect, when adding water in 80C room). Thank you to those knowledgeable out there.
Please can you solve a question based on heat change from water to ice?
Damn he really starting speaking enchantment table on my ass 😭
Thank you for this true video. If we could illustrate this problem of chemical bond and phase equilibrium value with other curve formula, like y=ax+b or y=ax^b, it's too hard.
Good looks
Your not the only one who has that idea.😁😁😁
Thanks
pls can anyone explain. so its certain that when a substance is losing heat, the rate at which it loses heat is not constant, so why is it that in these graphs the temperature is falling at a constant rate? as in that it is a constant slope? is it because the rate falls so minutely that it cant be recorded unless we are being very specific witht the temperature measurement?
I love you class ❤❤❤
"thank you The Organic Chemistry Tutor," we all say in unison
It's so frigging cold because of the enthalpy of evaporation in the UK you know this
Dude.. is the cooling curve in step 3 linear or not?
who else takin chem regents 2morrow?
ugh good luck :(
today :(
I sware
Temurture
Adding heat energy freezes water? ):
Jake Enders the freezing curve is an exothermic process, which was different from the heating curve. On the heating curve, he was talking about adding heat to the substance to raise the temperature. On the freezing curve, he’s talking about TAKING HEAT AWAY from the substance to lower the temperature. The x axis for the freezing curve doesn’t really mean the same thing as the x axis for the heating curve. Freezing curve is telling you how much heat u need to extract, and heating curve is telling you how much need you need to put into each substance. Hope that helps and good question.
@@JohnSmith-gh7br lol John smith ashkara ass
Mudlij Al-Zakwani u can’t talk, your name is a mudlij al zakwani
@@JohnSmith-gh7br don't cry you look like a kimasomaso anyways
@@JohnSmith-gh7br lmao u right😂😂
what type of reaction is a cooling curve?
fam are you dumb
@@ishaanjaipuriyar4585 you know what’s crazy it’s not even my question it was a question on a worksheet my teacher gave me
@@ishaanjaipuriyar4585 so go meet her and ask her that because that’s the reason why I’m asking this wurstio
endothermic
@@Salted.caramelo no its exothermic
Thx for explaining but I didn't understand anything cuz while watching ur video I was playing video games 🤣🤣🤣
Love from India 🇮🇳
thanks
This guy is the sole reason imma pass chem
This is on my chemistry final tomorrow, wish me luck guys
chem makes me want to kms!
I love uuuu
OK am lost with the equations
Not me telling myself imma study at 12 am me at 12 ill study at 1 pm me also at 1 pm
Me: you know what I'll wing it what could go wrong
Me:who failed the test and is surprised 😂
I'm watching this because im from asgard
Oh your from asgard too??
No
I forgot to do homework due tomorrow 🙂🫠
My teacher is gonna flip after i fail my chemistry test
my classmate watchong this at the smae time as me if you see this you suck LMFAOOO
Chemistry am I right?
Beans
I wanted to learn cooling curve not rocket sience
This isn't rocket science (2015 edition)
I fail my exam test. This graph I can't solve it.😭
Bout to fail mine tomorrow ☹️
About to fail mine tomorrow 😢
@@ofentsemogapi844 what’d you get?
@@ballerspro8310 60%
Thanks but speak up pleas give example of heat curve
Is it just me who heard him say "temature" or...🤦♀️
Hello kids, please don't become chemical engineers
temature
WTF , I'm an architect ,why I'm even doing her.
bro I have never hated a video more. WHY R U SO HESISTANT TOOO SPEAKKKK
bro why are u hesitant to learn from ur teacher? stop coming here trying to get mad at this man cuz u was thinking about freezing time to smash the girl next to u in class instead of paying attention.
Pronounce Temperature right please god
Stop being petty.... look at the effort JG is putting to help us.
He got a point if u got a problem dont watch it
Thanks Sir 🤘
So knowledgable, but I can't listen for more than 5 seconds with the way he talks. Someone tell.this guy a 'th' is not pronounced like an 'f.'
some people have trouble pronouncing certain things, rosey
OOF
Bruh
Can you be a little more charismatic?
his work speaks for itself. If u want charisma, I'm sure tour professor has plenty, that's why you're here...right?
Can you?
Its a free video, you should be here for good, clear explanations, which it provides. Not a good time.
Wow, people will literally find a reason to complain for anything
I totally agree with LSSJ and Angel. He teaches so patiently. If you are looking for pronunciation and charisma. You are looking at the wrong video. It is so much effort to teach chemistry and we are getting for free. Learn appreciate it. Thanks!
After a lots of time, SHITT THIS VIDEO IS COVER EVERYTHING up in my teacher 3 lesson. U ARE A GENIUS 🥸
Thanks
