Okay, so for this question, there's a couple of reasons why the metal pan might be very hot to touch, but the water may still only be warm.
00:13
I have two pictures here to help us understand this process.
00:17
So the first one is just the basic difference between conduction and convection here, which is picture goes along with the question.
00:24
Fantastic.
00:25
You have a lot of movement here in the liquid, which is convection with your water.
00:30
Water.
00:31
That is going to be different in terms of heat transfer compared to conduction, which is the solid metal.
00:38
So that basic physics there is going to be part of the reason why the metal pan is heating up faster.
00:47
Another reason is because the metal ions are better at conducting heat than the water molecules.
00:55
And if you look at the right, the water molecules is two hydrogen, and one oxygen.
01:00
This is called polar, p -o -l -a -r, and that is referring to how part of the molecule here is slightly positive from your hydrogen molecules, and part of the water is slightly negative from your oxygen molecules...
