Question

devon places sliced potatoes in a package of aluminum foil. he puts a metal grate over a campfire and sets the package on the grate. he warms his hands over the fire while he waits and watches the hot air carry ashes into the sky. when he removes the foil package, the grate and foil are hot, and the food is cooked. which part of this scenario represents conduction?
the food cooks inside the foil.
devon warms his hands over the fire.
the hot air rises into the sky.
the grate is hot when devon is done cooking.

Explanation:

Conduction is the transfer of heat through direct contact. Devon's hands warming over the fire (direct contact with heat source) represents conduction. The hot air rising (convection), food cooking inside foil (could involve conduction but the key here is hands over fire), grate being hot when done (could be from conduction but the action of hands over fire is more direct conduction example).

Answer:

Devon warms his hands over the fire.
