Answer the following questions:

 

 

Due to the large surface volumesmall surface arealarge surface areasmall surface volume of hot tea (or milk) taken in the saucer, the evaporation of hot tea (or milk) from the saucer is faster. The faster distilationvaporisationdecompositionevaporation cools the hot tea (or milk) much faster, making it convenient to sip (or drink). Hence, we can sip hot tea or milk faster from a saucer than a cup.

 

 

During summer, we usually wear light coloured cotton clothes. We sweat a lot in the summers. Cotton is a good absorber of sweatgood absorber of heatgood absorber of waterbad absorber of water. Thus, it absorbs sweat from our body and exposes the sweat to the atmosphere, making its decompositiondistilationevaporationvaporisation faster.
