Thinking Point 8.5

Postby Chiao-Wei Cheng 3e » Fri Jan 13, 2017 4:58 pm

At the end of section 8.5, the thinking point was "Why does a hot pan inside a heated oven scald our hands when we touch it, but the air inside does not?"
My answer is that the molecules in the pan is densely packed and holds more heat than the loosely packed molecules in the air, where the heat disperses quicker.
I'm not sure if that is the right explanation, but can I get some clarification on this question?

I was wondering about that too. My thoughts were that the metal is a better conductor than the air and since there is no phase change of the pan turning into a liquid or vapor, the pan itself is the only thing that can scald you.
