Question

The water tanks kept on the terrace for storing water are coated with black color. give reason

Answer 1

Answer:

Whenever water will be consumed, safety becomes an issue because the growth of both algae and microbes must be inhibited. Many algae and bacteria are light sensitive. Exposure of the water to sunlight can raise the rate of growth many times over what inhibited exposure would allow. Therefore, blocking the sun from the water contained inside becomes a primary consideration in the selection of plastic tanks for major water containment. All other factors being equal, the black color will block out the most light from the interior of the tank.
