Question

(a) You want to wear your favourite shirt in a party, but the problem is that it is still wet after a wash. Mention three steps with reason that you would take to dry it faster ?
(b) 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 ?

Answer 1

(a) (i) Squeeze the shirt with force. By doing so, some of the moisture is removed.
(ii) Spread the shirt on a stand. It provides greater surface area for evaporation.
(iii) Iron the shirt. Increase in temperature helps in drying the shirt.
(b) Cotton clothes would be more comfortable than the nylon clothes since these are porous. Perspiration sticking to the skin can escape from the pores. Priyanshi would feel more comfortable.
