Heat flowing between two places when there is a difference in temperature?

Question

what is the above statement linked with out of the follwing:

conduction

convection

radiation

or all 3?

Answer 1

Any, or even a combination, of those 3 are possible, as they are the three ways of energy transfer.  Thus, since no specific situation is described, I would say all 3.

Answer 2

if it involves contact then it is conduction.

Answer 3

Conduction is transfer of heat via direct contact. Convection is the transfer of heat via motion. Radiation is transfer of heat via emittance. I'm going to go with conduction because its the most likely scenario.

Answer 4

I would say all three.  the question doesn't give enough information for you to figure out exactly how the heat is being transfered.

Answer 5

Heat always flows from high temperature to low temperature. And it is called as

                                                   Conduction.
