a) Electric wires have plastic coating as plastic is an insulator and prevents us from getting electric shock by not allowing the current to pass through it .
b) Cooking pans have handles made of plastics because plastic is a bad-conductor of heat and thus do not gets heated quickly and we can easily handle the pan .
c) Clothes made of synthetic fibres are not comfortable to wear especially in summers because in summers they aren't able to soak the sweat of our body and thus makes us feel uncomfortable and we need to be very careful while wearing synthetic clothes as they start melting on heating , if sticks to the skin then might cause severe burns .
