Why do we prefer

Answer :

The rate of vaporization increases with an increase in surface area. Saucer has higher surface area so it is easy to sip hot tea with saucer. So there will be more hot particles form into vapor and cool down the tea. In the cup due to less surface area less hot particles will be at the surface, so there will be less hot particles convert into vapor and cool down of tea will take more time.
