Isaac wants to make s'mores. 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.
