Evaporation is an endothermic process and is a surface phenonmenon. The rate of evaporation is more if surface area is more. The hot beverage will be cooled quickly in a saucer, as the surface area is high and heat is transferred from the liquid moving to the vapour state. Hence drinking is easy and quick.
