Why are we able to sip hot tea or milk faster from a saucer rather than a cup?
The more surface area , the faster is the rate of evaporation. Since the surface area is more when tea/milk is in the saucer as compared to that when tea/milk is in the cup, the rate of evaporation is faster in a saucer. Hence, we are able to sip hot tea or milk faster from a saucer rather than a cup.
