When you sit by a campfire, most of the heat you are receiving from the fire does not come from hot air. It comes from thermal radiation.

Answer 2

$\huge{\underline{\boxed{\mathrm{Answer}}}}$

→ When you sit by a campfire, most of the heat you are receiving from the fire does not come from hot air. It comes from thermal radiation. This radiation carries energy which is converted to heat when it hits another object and is absorbed. In contrast, conduction involves the direct movement of heat through an object.
