Answer:
Kate gathered three boxes of the same size made of different materials: glass, clear plastic, and aluminum painted black. She placed them on a window sill in the sun for an hour and then measured the warmth of the air in each box. This was done to relate the type of box material to the warmth of air within the box.
Step-by-step explanation:
Even though all the boxes were placed in the sun for same time, all the boxes will have different temperatures. This is because of the nature of the material while absorbing different amount of heat. Even the color of the materials matter in this case.
