Detailed Solution

The above statement is false.
In a saucer as opposed to a cup, a liquid has a wider surface area. Surface area is thus one of the elements influencing evaporation. The amount of evaporation increases with surface area. Because evaporation occurs more quickly in a saucer than in a cup, greater cooling results. Because of this, we can drink hot tea or milk from a saucer more quickly than a cup.
The correct statement would be, “We are able to sip hot tea or milk faster from a sauce rather than a cup”.
