The Physics of Heat: Crash Course Physics #22

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep you warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Shini talks about the physics of heat!

After that intro, I expect these comments to be civil and respectful.

The lightbulbs fall neatly on her head and shoulders. This is quite satisfying.

[cassierodriguez]

Thank you so much! I literally just watched 5 videos and learned more from you than my actual professor! He's great, but you provide examples that apply to everyday life so it makes more sense to me! Thank you, I feel way more confident for my last midterm

Great video as always, Shini! Thermal engineer here. Man, you went through basically three semesters worth of thermo & heat transfer in the last three videos! Isn't this your sort of intro to physics series? We didn't cover some of this stuff until second or third year of undergrad. Anyway, keep up the good work!

[chaotcmind]

damn you just went through the thermodynamics of my first two years of college in a 10minute video

[EugeneKhutoryansky]

The real reason for wearing clothes is social convention. In warm climates, it is not really necessary.

[sanjaychintapally]

This video has given me all the answers I needed about heat and heat transfer. Thanks a lot!

[LeMasterYi]

10 minutes videos that take 100 minutes to study them.I love these.Atleast they make things clear!

[Rararasputin]

This helped so much!! We just did this in chemistry and I was confused!!! Thank you!!

[gabrielschilive]

I loved that episode, congratulations, I am studying thermodynamics and things related to heat and temperature, and that episode helped me a lot with this, so thank you VERY much Crash Course, and thank you also Dr. Shini Somara for your great host-work, you all are amazing.

[erasmith]

Very simple U guys r the Thank u so much

About the losing heat from not wearing clothes, I've found that to be true only temporarily.

Turns out that the body adjusts its own temperature, as long as it isn't too cold. I've been just as warm naked as with a sweatshirt.

i like how crashcourse draw their heat diagram to scale

[lorennebedminster]

since I'm possibly the only serious person here, I'll share what I learned today.
1.Clothes have a reason (I wasn't so sure)
2.I suck at Physics
and
3.E=mc2

"Heat"

"Naked people on thumbnail"

Oh.. you meant... you meant the physics definition of heat. That makes more sense.

That was quite an interesting, informative video, I loved it it was fun to watch and it made my thermal energy exam preparation easier so great thanks for sharing such good content ❤️.

[deemon]

I could follow this one better than most others. Thanks!

[LeahMonroe]

Great course, its always easier to digest when you already have applications

[sudharsanvj]

Loved the examples of conduction and convection
