Question

isaac wants to make smores. he holds a marshmallow on a metal skewer over a fire. a few seconds later, the marshmallow is cooked and the skewer feels warm. what most likely happened? the fire heated the surrounding air, which cooked the marshmallow. the heat generated from the marshmallow flowed in the form of thermal energy to the skewer and fire. the heat from the skewer cooked the marshmallow. thermal energy in the form of heat moved from the fire to the skewer and marshmallow.

Explanation:

Heat transfer occurs when there is a temperature - difference. In this case, the fire is the heat source. Thermal energy (heat) moves from the high - temperature fire to the lower - temperature skewer and marshmallow. The fire heats the skewer and marshmallow directly through conduction (since the marshmallow is on the skewer and the skewer is in contact with the fire).

Answer:

Thermal energy in the form of heat moved from the fire to the skewer and marshmallow.
