Answer 2

Concept

The given assertion and reason both are correct but it is not a correct explanation for this assertion.

Explanation:

• We should not use synthetic fabrics while working in the kitchen because synthetic fibers can catch fire easily and they are not fire resistant and also they melts easily can cause severe burns to the person working .

• Hence, it is not advisable to use synthetic fibers while working near fire.

• Synthetic fibers are made from modifications in natural fibers.

• As example , Rayon is a regenerated cellulose fiber made from cellulose.

• Synthetic fabrics dry up quickly and are easy to wash because they absorbs less water compare to the natural fibers.

• Natural fibers ( e.x., cotton) contains cellulose which forms hydrogen bond with the water molecules and because of that water can not evaporate easily and take much longer time to dry.

• While in case of synthetic fibers, water is bonded physically so it is much more easy to evaporate rather than having chemical bond like hydrogen bond.
