. Sweating causes cooling by

(a)   Conduction

(c)   Radiation

(d)  Convection

(d)  Evaporation

Best Answer

The Correct Option is (b)

When radiant heat falls on a body, a part of it is absorbed and the rest is reflected. How much radiant heat of a body absorbs and how much it reflects depends on its color and the nature of its surface. Shiny, white bodies are the best reflectors, while rough, black bodies are the best absorbers of radiant heat. Black bodies absorb and emit radiant heat at the best.
