Explaining a Process-2

It’s easy to prove that the black collector of solar energy is better than the white one. What you need to prepare are two tin cans, a black and white paint and a room thermometer. Firstly, paint the cans-one black, one white. Then, fill the cans with water. After that, put the cans in direct sunlight for three hours and check the temperature of the water in the cans and compare. You will find that the temperature of the water in the black can is higher. It shows that the black collector of solar energy is better than the white one.
