Thermoworks DOT Thanksgiving 2014 Giveaway! As you know, heat is very important in the cooking process. Since the egg is in direct contact with the hot pan, the heat transfer is conduction. Examples of this can be seen at a stove. However, in addition to thermal radiation, heat transfer also occurs via thermal convection and thermal conduction. It states that conduction, due to the fact that air is a good thermal insulator, is of least importance in the heat from a campfire. These collisions transfer energy from the stove top (the burner) to the pot via thermal conduction. When a raw egg begins to fry as it hits a heated frying pan, energy from the pan moves to the egg and cooks it. Here's a simple mental picture to have of a how a burner on a stove heats up water in a pot (which is sitting on the burner). "Signpost" puzzle from Tatham's collection.

Thanks for contributing an answer to Physics Stack Exchange! What is part of heat transfer that is found in a theater? 4) "Pot molecules" near the water on the inside of the pot can now begin transferring their kinetic energy to the water molecules via collisions (because all the molecules are vibrating). We expect that, where c is some constant, $P_{rad}$ is the radiation energy output of the fire experienced by the marshmallow at distance r, and $P_{conv}$ is the convective output of the fire experienced by the marshmallow at distance r. Thus with both these quantities we can measure the relative strength of convective and radiative heating, Caveats: I assumed crucially that the radiant power output of the fire is the same in all directions (so that $P_{rad}$ is the same quantity in both $t_h$ and $t_v$).
