Explaining a Process--2

If you want to show that black is a better collector of solar energy than white, you can conduct a simple experiment.  What you have to prepare are two tin cans, black and white paint and room thermometers.  First, paint the black can and the white one as well.  Next, fill the both cans with water.  Then place the cans in direct sunlight for three hours.  Three hours later, you have to check the temperature of the water in the cans and compare the two.  Finally, you will find that the temperature of the water in the black can is higher than the white one.  The experiment proves that black is a better collector of solar energy than white.
