Because of the small surface area the evaporation of hot tea taken in the cup is slow ,cooling caused by evaporation is less ,and hence the hot tea or milk remains hot for longer time ,making it difficult to sip .on the other hand ,saucer has a large surface area. Due to the large surface area of hot milk taken in saucer ,the evaporation of hot tea from the saucer is faster.

As saucer posses larger surface area than cup thus latent heat of vaporisation is faster in saucer hence we are able to sip hot tea or milk faster
