What absorbs more heat, aluminum foil or black paper?

black paper

To determine which material absorbs more heat between aluminum foil and black paper, we need to consider their specific properties.

Aluminum foil is known for its high reflectivity. It reflects a significant amount of incoming heat radiation, making it a poor absorber of heat energy. On the other hand, black paper is often used to enhance heat absorption due to its dark color, which allows it to absorb a greater amount of heat radiation.

Now, to empirically compare the two materials:

1. Obtain a sheet of aluminum foil and a sheet of black paper.
2. Place both materials under identical conditions, preferably in a sunny area or in front of a heat source.
3. Leave them exposed for a specified period, ensuring they are equally exposed to the heat source.
4. Use a thermometer to measure the temperature change of each material.

After following these steps, observe and compare the temperature changes of the aluminum foil and black paper. If the black paper shows a higher temperature increase, it signifies that it absorbs more heat compared to the aluminum foil.

Keep in mind that this experiment may vary depending on the specific environment and heat source used.
