during winters we wear dark clothes because they absorb a lot more heat. to do this experiment
take two aluminium cans. one colored black and the other should be shiny aluminium. now
fill both the cans with same amount of water. fill both the cans to the to. then take two
thermometers and place one in each can and measure initial temperature of the water.
then keep these cans in the sun outside for almost 3 hours. after 3 hours you will be
surprised that the temperature of the black can would have risen by 6.5 degrees. which
means that the black can has absorbed lot more heat and the water has become warm.
