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.
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
Because it is 333 kJ (kilojoules) but when you put the number into the equation it has to be in regular joules and not kilojoules. So the 333kJ can be written as 333,000 J or 333 x 10^3 J. Does that help?
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?
@@stepbystepscience doctor is it possible for you to solve a few more questions that has a unique way to solve? For example, not having a mass not density but having a volume, or dropping an object into water, you know those vary kinds of questions. This would be so helpful and appreciated and i will make sure to share it to all my classmates.
In the Rankine steam power plant, 2 kg of steam at enters the condenser. Determine the amount of heat rejected by the steam in the condenser to change its phase from vapor to liquid in an isothermal process. Take the latent heat of vaporization of water is 2260 kJ/kg. Please help solve this
what would happen if you reversed the equation so that i would be able to use it to find the energy transferred away from 100g of steam @ 100 degrees to change it to a liquid?
please solve this proplem, How much heat energy is required to change a 40 g ice cube from a solid at -10 degree centigrade to steam at 110 degree centigrade?
Morning okay this examples of finding of specific latent. Heat of evaporation of water how much of mass is12kg and heat energy of536joules and temperature is 30 to40 find the. Specific heat energy 😂

Glad it helped and best wishes for the exams!!
It is so helpful to me.i have searched this type of video for 30 minutes. At last i found it.
I'm glad it was helpful! Thanks for the comment.
Excellent explanation! Earlier I had confusion in solving such questions but now its crystal clear!
Great to hear, thanks for the comment!
Been watching your videos since I was in high school!!! Thanks for putting the time and effort into making these videos!
So nice of you. Thanks for the positive feedback!
Perfect, short, sweet, and to the point.
Thanks very much. Glad you liked it!
The answer was supposed to be 1277525 J or 1277.525 if you add all of them. I was confused for a second there.
Very true brother
Same thoughts
hi, i think u have made a calculation mistake. It should be 1277525 Joules
Yeah,I calculated it too
You have made it well, thanks to you for that great help. You're now better by far compare to my current lecture🙆
You're welcome. Glad to be of help!
This was great. explains how I will calculate energy use in my up and coming lab. thank you
Glad it was helpful! Thanks for watching.
very instructional and clearly explained, thank you
Glad it was helpful!
Thankyou u literally helped me so mcuh to recap.. i hv a test tmr. thankyou!
Best of luck!
Thanks a lot. I've got a science test coming up and this was very useful :)
Best of luck on your test!
@@stepbystepscience thank you
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
You're welcome and hope the test went well!
Really descriptive and helpful.....!!
Glad it was helpful!
Amazing explanation.
Glad you liked it, thanks
Im wondering where did you get the 10^3?
Because it is 333 kJ (kilojoules) but when you put the number into the equation it has to be in regular joules and not kilojoules. So the 333kJ can be written as 333,000 J or 333 x 10^3 J. Does that help?
I have a question. I'm kind of confused,so when we calculate latent heat do we not convert the °C into Kelvin?
Nope
Thankyou for brilliant explanation.
You are very welcome! Glad you liked it.
How we can make calculations for entopy change for same question
Good video 👍😁👌👍💯
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?
It helped me thanks sir ❤
Glad to hear that
Thankkk youuuu sooo muchh!!! you made my problems now very easy!
You are welcome! Glad to help.
Thanks doctor, this was helpful
Glad to hear that, you're very welcome!

enters the condenser. Determine the amount of heat rejected by the steam in the condenser to change its phase from vapor to liquid in an isothermal process. Take the latent heat of vaporization of water is 2260 kJ/kg.
Please help solve this
what would happen if you reversed the equation so that i would be able to use it to find the energy transferred away from 100g of steam @ 100 degrees to change it to a liquid?
You would get the same amount of heat out.
very good sir
Many thanks!
Is 333 degrees celcius is a constant value of Lf? and sir, why is it there is 10 raise to the power of 3?
Thank you so much
It helped
Fantastic, you're very welcome!
Imagine the world all teachers like this guy , thanks
Thanks so much!
please solve this proplem, How much heat energy is required to change a 40 g ice cube from a solid at -10 degree centigrade to steam at
110 degree centigrade?
This is basically answered in the video.
@@stepbystepscience the video did upto gas
Yes, but steam is a gas.
Thanks for vedio maker
Most welcome!
Xans sir for da explanation but ur somehow so speedy can u plz reduce da speed
Sorry, it is a balance between talking too slow and talking too fast. Of course you can always pause the video and rewind a bit if you need to.
Thank you so much :D
You're welcome!
Nice explanation, a student from Philippines here
Thanks! 😃
nice explanation.
Glad it was helpful!
i did it and i ended up with 1277525, don't know why
Good explanation
Thanks and thanks for the comment.

God bless
Where is the -15 degrees Celsius
Right next to the -14 degrees Celsius.
Good video 👍😁😁👍
Thank you 👍
Sancho prof
Is that good or bad.
@@stepbystepscience lol its good, its a slang for thank you in Zambia
Uma brasileira 🇧🇷😔🇧🇷😔
Unfortunately didn't understand nothing yet .
sorry, feel free to ask a question and try listening again
.
It's not so helpful
Why not?
@@stepbystepscience because ur calculations are wrong
@@yoyoproboy9516 What is wrong with them?
