Question

While you are standing next to a fire, your body begins to heat up. This is heat transfer by

conduction

convection

aeration

radiation

Answer 1

convection is the moving of material from one area to another -- is that happening?

Conduction is the material between one place and another heating up -- is that the main thing happening here?

Radiation is the transmission of heat through light and other electromagnetic radiation. Is that what's happening here?

Aeration isn't a means of heat transfer.

Which of these four therefore is correct?

Answer 2

Let me ask you this. If you put a screen between you and fire, would your body still heat up? No, hardly at all.

Hence which of the three heat transfer mechanisms is the most important?

Answer 3

conduction

Answer 4

Why do skillets have wooden handles vs. metal handles? Because if they had a metal handle, it would get hot through conduction.

Conduction is not the mechanism whereby heat is transferred from the fire to you.

Answer 5

ohh i gott iht naw thnks:)

Answer 6

So what's the answer?

Answer 7

convection?

Answer 8

No. Look at the picture I just posted. Convection involves the moving of hot and cold atoms and molecules from one place to another.

That isn't what's going on with a fire. It isn't hot air molecules that heat you up.

It's radiation.
