Question

evaporation takes place at all temperature. then why do we spread our wet cloths to dry in the sun

Answer 1

the water to boil needs 100degrees temperature not to evaporate.Evaporation is a different phenomenon.boiling is a process where we are supplying heat energy to the water molecules to reach gaseous state,but evaporation is a natural and slow phenomenon,whetethe water molecules on the surface get mixed up with the air and move along.so,the clothes dries off even inside the room. it dries off fast in sun because hot air has less density and can carry more water molecules with them.

Answer 2

It says evaporation takes place at all temperature,we need to spread clothes as blowing of air above the surface carry away water molecules with it
