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 heat transfer through direct contact between materials. The hot aluminum foil (heated by contact with the hot grate) directly touches the sliced potatoes, transferring heat to cook them via conduction.

• Warming hands over fire is radiation.
• Hot air rising is convection.
• The grate being hot is a result of conduction from the fire, but it does not represent the conduction event that matches the question's focus on the scenario's heat transfer related to cooking/food; the food cooking via foil contact is the direct conduction example.

Answer:

The food cooks inside the foil.
