Question
Select the correct option for the characteristics of the polymer.
- High-temperature stability
- High mechanical strength
- High elongation
- Low hardness
Hint:
Polymers are giant molecules. They are important chemicals in our bodies, in plants, and in our everyday lives.
The correct answer is: High elongation
The combination of high tear strength and high elongation results in a material with high toughness. Elongation at break measures how much bending or deformation a material can withstand without breaking. The measured extension at break values indicates the ductility of the polymer.

Woollen clothes made up of wool are obtained from
The correct option is c)sheep.
Wool, an animal fiber that forms the protective covering or fleece of hairy mammals such as sheep, goats and camels. Prehistoric humans who wore sheepskin eventually learned to make threads and cloth from the fiber-covered material, which formed a protective outer layer due to selective breeding of sheep. Most of the long, coarse hair has been removed, leaving behind an insulating, fluffy undercoat made up of soft, fine fibers.
Wool is primarily obtained by shearing the fleece of live animals, but the fur of slaughtered sheep is sometimes treated to loosen the fibers, creating an inferior type called drawn wool.
