Question

state reason for the following
i ) dark coloured dress are not proffered on sunny days
ii) cotton bags are encouraged now a day
iii) nylon is used to make ropes

Answer 1

I) We prefer white coloured clothes in summer because white colour is poor absorber of heat and so they keep us cool during summer. On the other hand, during winter we prefer black and dark coloured clothes because black colour is good absorber of heat and thus they keep us comfortably warm during winter.

ii) Jute and cotton bags are made of natural fibers. These bags are biodegradable and reusable. Jute and cotton bags are an ideal replacement for plastic bags because these bags are degradable by organisms. ... Use of these bags help in reducing the use of wasteful and unwanted materials.

III) Nylon is a synthetic fibre which is very strong, even stronger than steel wire. Therefore, it is commonly used to make strong ropes.
