Give brief answers to the following questions:
 
It is a hot summer day, Priyanshi and Ali are wearing cotton and nylon clothes respectively. Who do you think would be more comfortable and why?
 
Sweating is a natural mechanism to keep our bodies . Our body sweats a lot on hot summer days. A cotton cloth absorbs sweat quickly, while a nylon cloth does not.
Evaporation of sweat absorbed by cotton cloth resulted in a effect on our bodies. The rate of evaporation also increases with the increase in surface area.
When one wears cotton cloth on hot summer days, it quickly absorbs the sweat coming from our bodies. The of sweat also increases as it is absorbed by the cotton cloth, which increases the evaporation rate. One who wears cotton cloth feels more comfortable because of the cooling effect due to the of sweat.
Hence, Priyanshi, who wears the cotton cloth, will feel more , while Ali does not.
