(N/A) Cotton clothes contain thin fibers that act like capillaries. Due to the phenomenon of capillarity,these fibers absorb sweat from the body. When this absorbed sweat is exposed to the atmosphere,it undergoes evaporation. Since evaporation is an endothermic process,it absorbs latent heat from the body,providing a cooling effect and keeping the body dry.
