Question

Most balloons, tyres and footballs are made-of rubber. This is because rubber is:
A) Naturally available
B) Cheap
C) An electric insulator
D) Soft and flexible

Answer 1

Hint:First we should be aware of the properties of rubber which makes it a perfect fit when it comes to the making of balloons, tyres and footballs. Now the main qualities that helps are the softness and the flexibility. Now this makes them more safe and technically more suitable.

Complete answer:
Here in the given question statement the question is regarding the nature of the rubber that allows the material to be an ideal approach when it comes to the product to be formed in the problem statement. They are rubber tires and the balloons.

A long time before the generation of the rubber tires, metal and wood were the materials which were most common in use. Then it was observed that natural Rubber provides better cushioning, and apart from that it also makes less noise.

Further on the qualities of the rubber it was noticed that rubber deforms under weight or force which eventually results in larger contact patch with the road than with metalor wood tires of the same diameter.

Apart from that during cornering at high speeds, the deformation of the sidewall and larger contact area improves the traction or grip on the road increasing safety.

Therefore the correct answer is (B).

Note:Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into rubber that is ready for commercial processing.
