Great video, Khan. I was searching all over the internet for a video like this. No one explains intuitively like you do - using particles to demonstrate conduction.
Thanks for this video. I have a question;' What if i used a device to measure the two materials? would they look as if they have 70deg or the metal would look cooler?
Thermal conductivity is also done through Free electrons but only in metals(free electrons are present in metals only). free electrons are another reason why metals conduct heat faster.

he is pretty good at drawing a hand..!!
Awesomely explained!!
Thank you so much.
This is very informative and useful to know in everyday life. Thanks Khan Academy !
Mind Blown ! .. Thanks
Very good video, thanks for sharing!
Wow, awesome. You made my day. Actualy,night.

No...they would measure at the same temperature though the metal would reach its steady reading faster.
Thanks you two
Love the intro
I like your sound man
Fahrenheit
Really
+MorenK1 yes. get over it.

so, what about the heat conductivity through the atoms held in air pockets ? As long as its not vaccuum pockets
Atoms in air pockets are vastly apart as compared with atoms in a solid, so they transfer heat at far lower rates.
isnt conduction based on free electrons and ions ????
Electrical conductivity does, not Thermal :D
Thermal conductivity is also done through Free electrons but only in metals(free electrons are present in metals only). free electrons are another reason why metals conduct heat faster.
wood vs metal >=3
