Question

Why can we drink hot tea or milk in a saucer but not in a cup easily​

Answer 1

We prefer to sip hot tea with a saucer rather than a cup it is because the saucer has large surface area compare to the cup,so the hot tea cools faster in the saucer. The rate of evaporation depends upon the suface area. More the area , more the evaporation.

Answer 2

It is easier to sip hot tea or milk faster from a saucer rather than from a cup because of evaporation. As we know that evaporation depends on surface area. If the surface area is more rate of evaporation is faster. And evaporation causes cooling. So if the surface area is more rate of evaporation is faster and so is the cooling rate. Hence we are able to sip hot tea or milk faster from a saucer rather than from a cup.

Hope this helps.
