Is cooking a hot dog over campfire radiation or conduction?

* Conduction: Heat is transferred directly from the hot coals to the hot dog through direct contact. The hot coals vibrate, transferring energy to the hot dog's molecules, causing them to heat up.

* Radiation: While some heat transfer through radiation does occur (infrared radiation from the flames), it's a much less significant factor compared to conduction in this scenario.

Think of it this way:

* Conduction: Like holding a hot spoon, the heat directly transfers to your hand.

* Radiation: Like feeling the warmth of the sun, the heat travels through space.

The hot dog is in direct contact with the hot coals, making conduction the dominant way heat is transferred.
