- This video covers specific heat capacity and uses the concept to explain why water is used as a coolant and explain why it coastal regions have differing temperature ranges than inland regions.

This video's are so great. Heat capacity is one of those concepts although simple definition you never have a physical sense of what is about. Thanks.
Anyone else here cuz their teacher made them
Yeah man lol
Same mr.lopez
E-Learning
Yup
Ese_Wey_ Eddie yup lmao
you made me want pizza.
Wow a 10 minute vid tought me more than a 1hr lesson in class
fr fr
cap you mean 2 lessons not 1 h
thank you! this is very helpful!
00:00 that doesn’t look like a pizza
I was confused when I saw pizza as a background in a physics video and now... I'm both hungry and know what specific heat capacity is
Thank you for this amazing explanation🙏🙏🙏 ❤❤❤🔥
Excellent explanation and application of the topic! Thanks!
Thanks.
that was excellent and made easy thank you
First 35 seconds, my mouth was watering
Thank you for helping me with my homework -w-
Really executive...thanks
Thank you for the succinct explanation.
You’re welcome.
Very good!
That pizza looks damn good
ty i understand it now
Wow you're amazing
What about the factors affecting the specific heat capacity???
If the kilograms (kg) were different: for example a block of copper at 1 kg is put into water at 2 kg, the specific heat capacity is 1480 and energy is what is required - how would you work this out? I was taught difference in temperature, not kgs. Thanks :)
Sorry, this answer is probably 6 months too late, but let me know if it makes sense to you! This problem requires a bit of roundabout thinking, so be patient:
Temperature difference works when you're dealing with a single substance. Because you have two different objects (one is water, the other is copper), you would have two different masses, and two different heat capacities as well.
Start off with the statement: "The heat lost from the copper equals the heat absorbed by the water"; in equation form, this reads:
Q (copper) = - Q (water)
Substituting in the heat equation, you can rewrite this statement in terms of mass, specific heat capacities, and temperature:
m * c * deltaT (copper) = - m * c * deltaT (water)
You also know that the heat transfer will stop when the copper and water reach the same temperature. With this in mind, you can rewrite deltaT for each material as (Tfinal - Tinitial)
m * c * (Tfinal - Tinitial) (copper) = - m * c * (Tfinal - Tinitial) (water)
At this point, you can plug in known values for m, c, and Tinitial for both copper and water, then solve for Tfinal
Once you've obtained the final temperature of copper or water, you can plug that back into Q = m * c * (Tfinal - Tinitial) for either copper or water and find the amount of energy that was transferred.
Thanks a million times sir.🙏🙏🙏
Always welcome
I have question from my textbook . Can anybody tell me about the specific heat capacity of water in different systems of units along with the conversion ?
1 Cal j/g C or 4.18 J/g C (Calories and Joules)
great one sir.
I learnt from Pakistan
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?
It's interesting
Thanks paul love from India. ❤️🇮🇳
youre welcome
@@PhysicsHigh i am again watching this cuz u replied... 😂❤️
Wow
8:38 . How do yu know that the heat capacity is 4182 j/kg/c° because it doesnt say anything about heat capacity in question.
It’s a standard value for water. Easy to look up.
If you know the mass, energy transferred (which can be easily calculated from the current, voltage and time taken to heat it up) and temperature rise in that particular time period then you can calculate the specific heat capacity using the equation: energy ÷ [mass x temperature change].
Also, if this was a question in an exam then the specific heat capacity would be given
@@PhysicsHigh is this value a fixed value? That means anywhere or anything we apply 4182 for specific heat capacity of water?
Another thing is when we bake pizza why the cheese get hotter faster than crust. The cheese should have low specific heat because it is heating up faster , but according to google search cheese is having high specific heat?
Is specific heat and specific heat capacity are same? If water has high specific heat , it means it has high specific heat capacity also?
that means when everttime we substitute for temperatioer do the have to be celcias
Actually kelvin is better. But since the scale is only shifted 273, you can use Celsius for specific heat capacity.
omg i am trying to distract my self form food while doing a fast, and there is this huge juicy pizza slapped onto my screen lol
👍
Salute to Mr Gordon o7
quack
q u a c k
Lmao get bodied
what is heat capacity
anyone notice that the value on the chart he gave for water is 4186 but when he uses it in his example he uses 4182?
Minor error. Sorry. Latter is the correct one
0:04 🍕🍕
I got raising many doubts after seeing this video
Someone help me why is 20-100 = +80 (Temperature)?
There he just want to tell us that the temperature change is from 20 to
100 and for that he needs an 80°c change.....
It is not like 20-100=80
0:01 that pizza looks tasty
8:16 is this man trying to boil himself?
Lmao get bodied
yo speak up, volume to low
my pc and youtube and browser volume are at the max and still cant hear him
I think you guys have a problem with your phones
Try using headphones
who cares about heat capacity, i rather use cool capacity.
