Burnt marshmallow is simply a marshmallow that has been extremely toasted! There are two main processes that heat a marshmallow: absorption of campfire radiation (photons) and contact with very hot air rising off the fire (convection). If we
place the marshmallow directly above the fire
, we get both.
What type of energy is roasting a marshmallow over a fire?
Convection
is the process of heat transfer that involves the movement of a liquid or a gas. In this case, when you roast a marshmallow above the fire where the hot air is rising, convection takes place.

electromagnetic waves
carry the energy. Electromagnetic radiation comes from accelerating electric charges. … Even you radiate all the time, but that radiation isn’t visible as light because it’s in the infrared part of the spectrum.
Is a campfire conduction convection or radiation?
An example of
radiation
is with a campfire, radiation occurs all around the campfire as energy travels away from the flame in the form of electromagnetic waves. Three ways that heat transfer can move from one place to another is called conduction, radiation, convection.
