Give Reasons for the Following:Why should we wear cotton clothes in summer? |
|
Answer» We perspire more in summer. Sweat present in the surface of our body absorbs the energy equal to the latent heat of vapourisation and gets converted to vapour. This gives a cooling effect to our body. This is called evaporative cooling. Cotton is a good absorber of water. Hence, cotton clothes absorb the sweat and expose it to the surroundings for easy evaporation. |
