Question

Most rubber bands and tyres are made of rubber. This is because rubber is:

• A. naturally available
• B. cheap
• C. an electrical insulator
• D. elastic and strong

Answer 1

The correct option is D elastic and strong

Natural rubber is a naturally available polymer. It is used to prepare rubber bands and tyres because rubber is

• Elastic; because of this property a rubber band can be stretched to 9 or 10 times its original length and when the force is removed it regains its original length.
• It is strong and tough. Because of this property, it can be put to use even under abnormal conditions. And is therefore used to make tyres.
