determining type of energy transfer\ndevon 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.\nwhich part of this scenario represents conduction?\no the food cooks inside the foil.\no devon warms his hands over the fire.\no the hot air rises into the sky.\no the grate is hot when devon is done cooking.

Answer

Brief Explanations:

Conduction is the transfer of heat energy through direct contact. The metal grate is in direct contact with the campfire, and heat is transferred to it by conduction. When Devon is done cooking, the grate is hot due to this conduction - based heat transfer. The food cooking inside the foil is more about heat transfer within the foil - food system, Devon warming hands over the fire is radiation (heat transfer without direct contact), and hot air rising is convection (heat transfer by the movement of fluids).

Answer:

The grate is hot when Devon is done cooking.
