Thermodynamics: Calculating Latent and Specific Heat, Example Problem

This video show how to calculate the heat needed take solid ice, melt it and then raise the temperature of the liquid water.

Latent heat is the heat added to or removed from a material to change the phase of the material without changing its temperature. Examples are latent heat of fusion which is the heat needed to melt or freeze a substance and latent heat of vaporization which is the heat involved in vaporizing or condensing a material.

Specific heat it is the amount of energy that must be added to or removed from one unit of mass of a substance (usually a kg or g) in order to cause an increase of one degree celsius (or Kelvin).

I'm from Jamaica and I have exams tmr and I never understood latent heat or specific heat capacity but this video and brian helped me a lot and now I am more confident that I will pass my exams...I am looking forward to watching the maths videos.

Perfect, short, sweet, and to the point.

It is so helpful to me.i have searched this type of video for 30 minutes. At last i found it.

[hellocoding]

Excellent explanation! Earlier I had confusion in solving such questions but now its crystal clear!

[shahin]

Been watching your videos since I was in high school!!! Thanks for putting the time and effort into making these videos!

[neylsonrodrigues]

This was great. explains how I will calculate energy use in my up and coming lab. thank you

[joelramos]

The answer was supposed to be 1277525 J or 1277.525 if you add all of them. I was confused for a second there.

[olivia_chen]

very instructional and clearly explained, thank you

[jehovahmanorriak]

You have made it well, thanks to you for that great help. You're now better by far compare to my current lecture🙆

[okila]

Imagine the world all teachers like this guy, thanks

[sharathbalachandra]

hi, i think u have made a calculation mistake. It should be 1277525 Joules

[pls]

Bro thnx so much for this video I was looking for a simple and short video and I found it. I have a physics test the same day so now I won’t be struggling. Thnx a lot

[jasminec]

Thankyou u literally helped me so mcuh to recap.. i hv a test tmr. thankyou!

[aedancharlton]

Thanks a lot. I've got a science test coming up and this was very useful :)

[ayeshakhalid]

Thankkk youuuu sooo muchh!!! you made my problems now very easy!

[markjustinenier]

Nice explanation, a student from Philippines here

[franklinetogoch]

Well explained 👏🏽. Now, can this concept be use to explain why it is easier to distill a solvent such as Toluene compared to water, considering the fact that Toluene has a higher boiling point than water?

Im wondering where did you get the 10^3?

[Alice-pwnt]

I have a question. I'm kind of confused, so when we calculate latent heat do we not convert the °C into Kelvin?

[nautiyal]

How we can make calculations for entopy change for same question
