Albedo and Heat Absorption Experiment
To investigate the effect of albedo, a student filled two identical boxes, one painted white and one black, with water and placed them in direct sunlight. The student predicted the water in the white box would heat more slowly than the water in the black box. However, the water temperature in both boxes increased at the same rate. Which of the following best explains a possible conceptual flaw in the experimental design?
The experiment was conducted for too short a period to observe the differential heating effect caused by the varying albedos.
The student used the same type of paint for both boxes, which had a similar thermal conductivity, nullifying the effect of color.
The boxes were not insulated, allowing heat from the environment to affect the temperature of the water equally in both boxes.
The student did not account for the fact that the water’s absorption of sunlight, not the color of the boxes, is the primary factor determining the water temperature increase.
