Question

Match the following: Plastic Types and Applications 

Code	Plastic Type	Common Applications
P	High-density polyethylene (HDPE)	(iv) Geomembrane for landfill liner
Q	Low-density polyethylene (LDPE)	(i) Garbage bags, bubble packaging
R	Polyethylene terephthalate (PET)	(iii) Water bottles
S	Polystyrene (PS)	(ii) Pharmaceutical bottles, Styrofoam cups

• A. P – (iv), Q – (i), R – (iii), S – (ii)
• B. P – (i), Q – (iii), R – (ii), S – (iv)
• C. P – (iv), Q – (i), R – (ii), S – (iii)
• D. P – (ii), Q – (iii), R – (iv), S – (i)

Hint:

Use the basic properties of plastics to remember applications: HDPE (strong) → landfill liners, pipes.
LDPE (soft/flexible) → bags, bubble wraps.
PET (transparent) → beverage bottles.
PS (lightweight) → disposable cups, trays.

Answer 1

The Correct Option is A

HDPE (P): Durable and chemically resistant → used in landfill liners.
LDPE (Q): Flexible and lightweight → used in garbage bags, bubble wraps.
PET (R): Transparent and strong → used in water bottles.
PS (S): Lightweight and insulating → used in pharmaceutical bottles, disposable Styrofoam cups. Final Answer: \[ \boxed{\text{(A) P – (iv), Q – (i), R – (iii), S – (ii)}} \]
