Kate gathered 3 of the same size made of different materials: glas, clear plastic, and aluminum painted black. She placed on the window sill in the sun for an hour and then measured the warmth of the air in each box. Which of the following best describes the purpose of the experiment? A) To relate the type of box material to the warmth of air within the box. B) to relate the type of box material to the mass of the box. C) to relate the amount of time a box is exposed to sunlight to the warmth of air within the box. D) to relate the size of the box to the warmth of air within the box.

To relate the type of box material to the warmth inside the box

Explanation:

3 boxes are made with three different materials glass, plastic and Aluminium. Thermal conductivity is different for different materials. thermal conductors allow easy flow of heat through them and insulators allow minimal or no flow of heat through them.

Thus the amount by which an object gets heated up depends on the value of its conductivity. In this experiment, glass and plastic are insulators and aluminium is a conductor. Among glass and plastic, plastic is a better insulator.

Thus the heat contained in the boxes will be of the order Aluminium>glass>plastic.
