Q 4. Why are we able to sip hot tea or milk faster from a saucer rather than a cup?
As we know, the evaporation is rate is faster with the increased surface area. Tea in a saucer has a larger surface area than in a cup.
Therefore, the cooling of tea is more rapid in the saucer, and thus, we can sip hot tea or milk faster from a saucer rather than a cup.
