(a)Evaporation is a process where liquid is converted into gas at any temperature below its melting point. Boiling is the process in which liquid is converted into vapour at its boiling point. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon.
(b)when we spread out the clothes, the surface area increases thus increasing the rate of evaporation. overall it results in drying up of clothes faster.
