Assertion: We are able to sip hot tea or milk faster from a saucer rather than a cup.
Reason: The larger is the surface area more is, the more evaporation. Thus, evaporation is faster in a saucer causing more cooling than in a cup. For this reason, we can sip hot tea or milk faster from a saucer than a cup.
