Warming your hands by a fire is an example if which heat transfer? Group of answer choices Radiation Friction Convection Conduction

Bubbly:

C?

Enderdude:

Conduction

Bubbly:

Thank you but, conduction is direct heat this is an example of warming your hands by a fire so im thinking C or A.

Enderdude:

It's Convection then because Conduction is the transfer of heat within the material itself. Most metals are good heat conductors. Wood is a very poor conductor so it transmits heat very slowly. This can be illustrated by the fact that a wooden handle on a hot frying pan remains cool enough to be held by the bare hands. Conduction is not an important factor in the spread of forest fires. so my fault

Bubbly:

thank you

Enderdude:

Welcome

Based on the phrasing of the question, the answer is not convection nor conduction, but it is radiation. Convection involves a transfer of fluid mass with varying temperatures or pressures. The heat felt from a fire is a product of radiation, which is why fire has various colors. If the question asked something like 'warming a pot of water with fire' or the transfer of CO in a room with a fire, then only convection is correct

SemiDefinite:

Most obvious effect is direct IR from the embers. Same as heat from the Sun, the science is the same.
