In this lesson, you will learn the difference between heat, temperature, specific heat, and heat capacity is in physics. Heat has units of energy, in Joules, and measures the transfer of kinetic energy on a microscopic level from one material to another. Specific heat is the amount of heat needed to raise a specific amount of material a specific temperature, usually 1 degree. Using these concepts, we can calculate how much heat energy is absorbed or released when an object increases or decreases its temperature. Fundamentally, it is related to the conservation of energy law..

I studied very similar applications in Machining School when we touched on heat and shrink fits. We had to calculate how much heat was needed to expand steel when installing sleeves and bearings. Love your videos. 🙏😌

At one time, I was considered to be a heat expert where I worked. I have long since retired and have lost a lot of info that used to be second nature. Thank you for bringing back most vividly a lot of that information. Although I'm now a fossel in my field, it is so refreshing to have your insight on all subjects. BTW, I hold a degree in Electronics Engineering Technology and am certified by the ISCET.

[@surprabhat1231]

The concepts are truly understandable for everyone who had watched video before

[@tresajessygeorge210]

THANK YOU... SIR...!!!

[@User-74891]

Thank you for very interesting lesson.

[@johnfox9169]

You have a nice combination of theoretical and "practical. Good work.

[@user-xs3us9rm4k]

So detailed. Thank you sir.

[@lilianadaranijo3689]

I don't know how to find the specific heat capacity

[@yfove8569]

but thx you very much you help me soooo MUCH ! if without you i'm going be lost الله يحفظكم

[@tsehayenegash8394]

what is the difference between work done on the system and work done by the system in physics?

[@arnoldnewton1299]

Thanks alot professor

[@surajshukla6813]

Thanks sir once again

[@DesmondMulenga]

Thank you

[@conjohn7174]

what is the difference between heat capacity and specific heat?

[@manojar20]

at 9:38 would Temperature not be measured in Degree Kelvin ?

[@richardserlin1317]

I have done a good deal of searching on the Internet, and I have not found a good explanation of the reasons why materials are better conductors of heat than others. It would be nice if you could provide this explanation, something a little bit more detailed than it has to do with what happens at the atomic or quantum level. Maybe this would require even a short addendum lecture, but it would be a nice contribution, as I did a good deal of searching and could not find anyone explaining this anywhere.

Where did you get the amount of gravity 9.8 ? Can you give some hint on it

[@saishatracy-wq2up]

9.8 is the constant unit of gravity u just have to know it

[@luckywhite7241]

The difference in temperature from the substance should have been (500-t) because it's obviously giving out heat to the water hence it final temperature will be less than 500.The temperature difference water will be (t -22)

[@user-ke6dg2ik8e]

This reminds me of chemistry exothermic and endothermic reactions 😂

[@eddieansumana9109]

Thanks alot....your explanations are clear and comprehensive

[@user-ke2xd9ig4g]

Thanks

[@bryanswanson5007]

Im from u.s. can this be done in btus/lb *f ?

[@felixyongco4420]

I can only recall in my study ( Physics 1 and Refrigeration 2 ) the formula : Q = mc◇T ( Btu ) long time ago. Thank you Sir Jason

[@drumtwo4seven]

Nice 👍

[@MathAndScience]

Thank you! Cheers!

[@GbadeboPrecious-ul6wd]

Sorry there's something I don't understand there Why did you divided the heat of the water by that of the heat of the pallet?

[@eddieansumana9109]

To get the number of pellets which caused the temperature of the water to raise from 20 to 25.

[@AyanyMakuacAyany]

Sir I don't know how calculate thermal expansion

[@vivianemekaenyinnia7401]

Good men

[@darebaylow]

You said the lead pellets have a mass of 1gram and are heated to 200 degree Celsius. I thought it means the final temp will be 200 degree Celsius (since it is heated to)

[@DesmondMulenga]

The final temperature will be 25 due to the fact that they are in water and are losing their initial heat ,I think you missed a point in the explanation in the being of the video 😊

math is a so easy for world

Dude really saved my ass

[@L4L-vh6qg]

Just wait for the answer n you'll see the answer

[@user-th5ui4ib3y]

44:13 Is this a mistake? -172.2 - 83720 does not equal -83540... great lecture btw!

[@RonaldGabica]

-83899.2 is the answer. Transpose the 83720 to left side, now they have same negative sign. Adding it you will get -83899.2

25:16 How did we get 10 to the power 5?

[@user-js4fm7ue5j]

How to find 4186 which is value of c

[@ianfowler9340]

Sorry to be a pig in the mud, but you really should be using "delta Q". Just using Q might confuse some students into thinking that you a referring to total amount of heat in the object rather than the amount added or subtracted. "delta Q" clears that up. i.e. the "delta T" forces the use of "delta Q"

[@MathAndScience]

I think your point is actually very well taken, and I agree. Thanks again so much for your feedback, jason.

[@ianfowler9340]

@@MathAndScience Love your approach. It is important to build from the ground up in small steps.

[@yfove8569]

heat is mean energy if H=-10 mean is heating if H=+10 mean is cooling see i am true science ! maybe not :(

[@louf7178]

"Heat transfer is energy in transition by virtue of temperature difference."

[@user-tq7wy9fs6s]

Am thinking the specific heat capacity is 4.18kg not 4186kg an confused

[@manumagar4512]

Guuuuuuuuu😂😂😂😂😂😂

[@VioletMalama]

Thank you

I don't know how to find the specific heat capacity

I don't know how to find the specific heat capacity

[@kathyoneill4011]

It is given to you. You don't have to find it out. Each material has a constant heat capacity
