How does the water kept in an earthen pot become cool during summer?
Why are we able to sip hot tea or milk faster from a saucer rather than a cup?
Answers
Step-by-step explanation:
Answer: We are able to sip tea, milk faster from a saucer because it has larger surface area than the cup, In larger surface area rate of evaporation is faster due to which tea or milk cools rapidly.
The water kept in an earthen pot remain cool even in summer because earthen pot has many small holes. Water seeps out through them and evaporates from the surface of the pot. The energy needed for evaporation is taken from the water kept in the earthen pot. As a result, water kept in earthen pot become cool.

Answer:
1) Water droplets come out from the walls through the pores and rapidly evaporated during due to high temperature. The amount of heat required for evaporation is acquired from the water of the pot hence water become cool.
2) The exposed surface area of saucer is more than, that of a cup due to which the rate of evaporation is saucer become more than the cup therefore the tea or milk in saucer cool quickly than the cup. Thus we are able to sip. hot tea or milk faster from a saucer rather than a cup.
