Question

What is the transfer of heat from a stove burner to a pan on the burner called?
conduction
convection
radiation

Answer 1

what d u feel?

Answer 2

convection

Answer 3

Nope./.

Answer 4

A or B

Answer 5

ok....when the pan is kept on the stove....THERE IS A PHYSICAL CONTACT between the pan and the stove.....- so now what do u think?

Answer 6

so...the pan gets heated by CONDUCTION......think like this.....the pan is metallic...so it has free electrons....when u heat the base of the pan, the electrons closest to the burner get energy and the oscillate or move about and COLLIDE with other electrons of the pan....hence the entire pan heats up...this is conduction

Answer 7

But if there was any water inside ,,then the WATER heats up by convection

Answer 8

Basic idea of convection is like this-" the water at the base heats up ,,,and when its temperature rises, it rises to the top....cold water comes to the base bcos its more dense,,,,again the same process continues till the end.....whole water heatsup

Answer 9

I believe AnthonyStark is correct, the way I saw the question is that there was a grill between pan and stove. Practical thinking I guess.

Answer 10

Ok....
The fundamental modes of heat transfer are:

Conduction or diffusion
The transfer of energy between objects that are in physical contact.
Convection
The transfer of energy between an object and its environment, due to fluid motion.
Advection
The transfer of energy from one location to another as a side effect of physically moving an object containing that energy.
Radiation
The transfer of energy to or from a body by means of the emission or absorption of electromagnetic radiation.
