Question

In places of hot climate it is advised that the outer walls of houses be painted white. Explain.

Answer in Brief

Solution

In hot climates, it is advised to paint the outer walls of houses white because a light colour such as white reflects back most of the heat that falls on it. Hence, a light colour tends to keep the house cool.
