Question

In places with hot climate it is advised that the outer walls of house painted are white explain why

Answer 1

In places of hot climate the outer walls of the house are painted white as we know that the white colour reflects the rays of the sun, whereas darker colours absorb the heat rays. So if dark colours are painted, the outer walls will absorb the heat and the house will get warmer. On the other hand, houses with lighter or white colours will reflect heat. This way the house will be comparatively cooler. I hope this helped you!! :)

Answer 2

It is because white colour reflects heat.That is why it is advisable to paint outer walls of houses with white paint.
