Loose-fitting white clothing covering most of the body is ideal for desert dwellers, both in the hot Sun and during cold evenings. Explain how such clothing is advantageous during both day and night.
In desert the climate during day is sunny hot while during night it is cold. The speed of the air is more too.
The white shirt doesn’t absorbs any rays comes to the sun, as the white surface have reflectivity 1. All the heat of comes from the sun is reflected back to the environment.
Hence the heat transfer through the white surface is negligible.
The ideal clothing for the desert dwellers is loose-fitting shirts which covers full body. Because the white shirt does allow the sun rays and heat to pass through it to the body during day-timing, while in night the heat from the body also doesn’t pass through the white shirt.
Hence the white shirt is bad conductor of heat.
