Tim and dan covered the inside of an open box in aluminum foil. they put a thermometer inside the box. then, tim and dan sealed the top of the box with plastic wrap. they put the box outside in direct sunlight. what type of energy do they expect to measure?

Heat Energy...

Explanation:

As it is covered with the plastic wrap and inside is covered in Aluminium foil. The temperature on the inside will rise eventually as exposure to the sunlight. This is because of the better thermal conductivity of the aluminium. The thermometer in contact will eventually give a high temperature reading based to the time of exposure.
