1.	Match the following .A. Teflon 1. can be blown up into large foam containing air bubblesB. Polystyrene 2. easily moulded can be rolled into thin sheetsC. Polythene 3. tougher than polythene,can coated on clothD. PVC 4. has high melting point and very low friction
Answer» Teflon => high melting point , very lowest FRICTION and non reactive. polystyrene => very light, can be blow up to her LARGE foam containing air bubble , in this FORM it is known as STYROFOAM or thermocol. polythene => easily moulded, can be rolled into sheet , strong and flexible. PVC => tougher than polythene , can be coated on a cloth base. so, A <=> 4 , B <=> 1 , C <=> 2 , D <=> 3
