Thermodynamics: Specific Heat Capacity Calculations
HTML-код
- Опубликовано: 2 авг 2024
- This video explains how to calculate the change in heat, the change in temperature and the specific heat of a substance. The change in heat is calculated as the mass of the substance times the specific heat of the substance times the change in temperature of the substance.
Q = m x c x T
Specific heat is defined as the amount of heat needed to change the temperature of one gram of a substance by one degree celsius.

Thank you so very much for helping me to understand how to use the heat equation. I was having trouble of understanding myself through the book.
You're very welcome!
I do have exam 10 mins. from now and this is really helpful. Wow! Just wow! Keep it up there's a lot of individuals who need your teaching. Easy and simple to understand. God bless.
So glad it was helpful, good luck on the exam!
This really helped me with my exam tomorrow, thank you sooo much!❤
I'm so glad, good luck!
Thanks so much man I have a better understanding of this topic now!! I have 3 chemistry tests coming up now in the run up to my actually GCSE exam on friday. So 3 tests in a row. I have to revise on thursday but this saved me so much time!! Thanks!!!
Best of luck with all the tests!
Jeez man, you have no idea how helpful this 4 minute video was compared to everything my teacher was trying to teach me....thanks for the help man👍🏽
You're very welcome! So glad it was helpful. Best wishes.
very helpful..thank you so much.
These videos are so nice. I love that you have things done beforehand in text and don't write sloppily.
Thanks for the comment. I used to write them out but also find it is better this way.
Thank you! I have a quiz on this tomorrow and didn't really get the concept, this video helped greatly!
Glad it helped! Good luck on the quiz.
damn this made it look easier now, thanks for this
My pleasure, thanks for watching!
I got an exam 2moro and it was really helpful...tq so much
Happy to help, good luck!
Ty
This is legit,I’m confusing about what is the definition of the equation and this video explains all of it
Thanks, glad it was helpful!
Thanks, I haven't even watched the video yet but I know it will help me much more than before
Thanks so much!
you absolutely rock. ive been searching the internet for hours trying to learn how to do this. thank you so so much. question. how do you know when to use a negative? (sorry for the grammar issues... im tired)
The change in temperature is always final minus initial and then the change in heat can be negative if the rxn is exothermic.
This made everything click for me
Thanks!
That's great, you're welcome!
u r such a great teacher
That is very nice of you to say, thanks a million!
At 1:53 shouldn’t delta Q be 7824080 J or 7.8 x 10^6 J in scientific notation? This is what I got from the calculation, do check this whenever you have free time. Thank you.
Appreciate you 👍🏾
Thanks so much!
Thanks . It was very helpful
Glad it helped
im learning for the last exam of my year and this really helps :>
Good luck, glad the video was helpful!
Why did I understand a month of work in cupple of min. Thank you kind sir for taking the time for making this video
You're very welcome!
Well explained thanks 😆👍
Any time, thanks for watching!
Thank you
Welcome!
Life changing. A moment of my life that I'm so proud to myself that I solve those problems without the help of my classmates.
That's wonderful!
Thank you so much sir
Most welcome, all the best.
Helpful but I want to know how we could apply to liquid in no atmosphere or vaccum condition
Thank you so so so much. I have understood every concept . Thank you so much dude
You are most welcome. Glad to be of help!
@@stepbystepscience Brian, i have recommended your channel to some of my friends. They said they loved this session. A small request- Can you please make a whole session about "Refraction of light at curved surfaces". We would really be grateful if you could please make a video on that. Waiting for your reply.....
Good suggestion, I will add it to my list....
This is truly an amazing video
Thanks so much, glad you liked it.
💯
thank you so much bro i understood very well
Glad to hear that.
thank you very much!!
You're welcome!
I didn't understood this but thanks 2 you I got 8 out of 10
Way to go!
damn you are so good,
thanks for the explaining
You are very welcome.
i appreciate your brevity
Thanks so much!
This helped me so much online classes are kinda confusing thanks !
What does it mean by calculating the magnitude of the energy charge of a metal?
"Energy charge of of a metal" never heard of it.
Thanks man, this saved my ass today
Excellent!
You're better than Our Prof.
How about this? "How much heat is needed to change 0.10kg of ice at -20ºC to steam at 110ºC?"
thank u
You're welcome!
You are giving us the specific heat of the substances. Can you show us how to solve for them?
thanks
You are very welcome.
Hi thanks so much for the video, if you see this please may you explain why you divide the specific heat by 1000 in the first question its just a bit confusing. Thanks so much
Yes, my error, I did not divide by 1000 the specific heat is 4.148 J/gC, but I used a comma by mistake, instead of a decimal point in the question part. I am currently teaching in Germany where they use the comma and the period opposite to the way you do in the US. Sorry for the confusion.
How do you calculate that if the question added time now
solve the equation for time
Thank you so muchh...i didnt understand it before when mtmy teachers thought it to us...but now i already do...(i hope my teacher would not read this comment hehehe)...but the thank you this video is really helpful😊😊
I'm glad to hear that it was helpful. Thanks for your comment.
Is specific heat constant? For example specific heat for Aluminum.
For any material the specific heat is a constant.
Can someone solve this question? Do I need to refer steam table to find the value of specific heat, specific latent heat & specific heat of steam as those information are not given?
The question are as follows...
"Determine the amount of heat needed to completely transform 1 g of water at 15°C to steam at 115°C".
hi. i was doing a experiment to measure water specific heat capacity in a controlled environment with high precision temperature measuring equipment and energy meters, vacuum insulated water container, 4.5kg of distilled water-to minimize the errors, i was stirring the water to avoid temperature stratification and every single time i got values for Cp around 4724 J/kgC. I run out of ideas of what could create the difference. Can we find out who and when and how were calculated values for water what we take for granted? i calculated the thermal losses to minute values and still doesn't get even close to the book values for water Cp-the difference is too high. Can anyone please give me an idea?
I am not sure what could be going wrong.
Thank u😁
You are very welcome.
How to solve this question?
300g of water at temperature 40 degree celcius is mixed with 900g of water at temperature 80 degree celcius. If there is no heat loss to the surrounding, what is the final temperature when thermal equilibrium is achieved by the mixture of water?
i tried to calculate 1975÷150×0.452 but the answer was wrong. how?
Grazie
Welcome!
how about the temperature is in K? Am I going to convert it into °C?
If the temperature is given in Celsius just add that to 273.15, because 0 C = 273.15 K. For example, 25 C = 298.15 K.
AN LIFE SaVERRR LIKE MY HERO HONESTLY
Thanks so much!
When a 45 g sample of an alloy at 100 C is dropped into 100 g of water at 25 C, the final temperature is 37 C. What is the specific heat of the alloy?
Did you watch the video
Since my first language is not English at first it confused me. By the way thanks I already figured it out.
Hello good eve can I know how do you get in your last problem the answer of 0.236?, because I get 4 233.009
Thank you
The problem In my book says 6.2 liters of water, what do I do
What is the formula for mass?
what do i do if i change the g to kg does that affect both m and c? i tried converting the two by 1000 to convert it to kg and did the basic Q=mc^T but it did not work? cause here in Australia we use kg instead of g
Why we convert g into kg because si unit of mass is kg please clear my doubt
You can use either one, grams or kilograms. It is just that usually in school you only have grams of a materials so I used grams.
You know what... some things just aren't for me give up happiness is forever life and science is temporary
I like to think science is fun.
2:42 did you mean 29.1C?
Yes, sorry I misspoke.
@@stepbystepscience it is ok. Thanks
Delta T can be measured in K
yes
why the comma at 1:52??????????????????
Because it is 7 thousand....
How about in fish meat how or what is the formula for freezing 25.30kg of fish???
😅 I'm sorry for my question.
For example 3 minutes
On 1:42 why is it 4.184? Why isn't it 4,184?
Wait nevermind. I should've watched the entire rest of the video. Thank you !
You're very welcome!
anyone got chem exams this week
Good question.
😇😇😇😇😇
😇😇😇😇😇
ur cool
Thanks dude!
noise
please do not use a comma where not needed, it confuses me with *.*
I am American and follow US English grammar.
Helpful, but you're talking WAYYY to fast
Sorry.
Slow down the playback speed
Had to slow the video down because you talk so fast😭
Sorry about that!
U sound drunk
How else do you think I am able to make all these videos? Thanks for the comment.
Yes, u should talk slower, ur viewers are not all english speakers
You can just slow the video down
Thanks but I couldn't understand your accent.😔
Sorry about that. I have a standard American accent.
these video is bad i wont share it to anyone
What is wrong with it?
Thank you
Welcome!
