Which of these is an example of a synthetic polymer?

Protein

Cellulose

Polyvinyl chloride (PVC)

Natural rubber

None

What is the defining characteristic of a superconductor when it is cooled below its critical temperature?

It becomes a perfect insulator.

It develops extremely high electrical resistance.

It exhibits zero electrical resistance

It converts electrical energy into heat energy with 100% efficiency.

None

How do fiber optic cables transmit information, making them advantageous over traditional copper wires?

They transmit data as signals of light, allowing for higher speed and capacity

They use superconductive materials to send electrical signals with zero loss.

They vibrate at high frequencies to transmit data acoustically.

They use magnetic pulses, which are not affected by electrical interference.

None

Photochromic glass, which darkens in sunlight, is created by adding which substances to regular glass?

Silver chloride (or silver bromide) and copper(II) chloride

Yttrium barium copper oxide

Polyester resin and glass fibers

Styrene and butadiene monomers

None

Which of the following pairs correctly matches a natural polymer with its corresponding monomer?

Protein and Amino acid

Carbohydrate (Starch) and Isoprene

Natural rubber and Amino acid

Protein and Glucose

None

The text identifies a major environmental issue with the disposal of advanced materials in electronic products. What is a primary reason that electronic waste (e-waste) is so harmful?

It absorbs a large amount of water, leading to soil dehydration.

It biodegrades too quickly, releasing nutrients that upset ecosystems.

It is highly radioactive and requires specialized containment.

It is often disposed of through open burning, which releases toxic gases.

None

Fiberglass is a composite material valued for being strong, lightweight, and corrosion-resistant. What are its two primary components?

Carbon atoms and polymer chains

Silver chloride and regular glass

Glass fibers and polyester resin (a type of plastic)

Steel rods and concrete

None

Nylon, commonly used for ropes, carpets, and clothing, is a synthetic copolymer. What does this imply about its monomer composition?

It is made from a single, complex monomer called ‘nylonene’

It is a modified version of the natural polymer, protein.

It is formed from two different types of monomers, hexanedioic acid and hexamethylene diamine.

It is made from repeating units of the natural monomer isoprene.

None

Styrene-butadiene rubber is used to make vehicle tires. Based on its name and the provided text, what type of material is it?

A superconductor

A natural polymer

A copolymer

A ceramic composite

None

10.

Reinforced concrete, used in bridges and skyscrapers, is a composite material made of concrete and steel rods. Why is this combination superior to concrete alone?

The concrete protects the steel from conducting electricity

The steel prevents the concrete from ever cracking.

The steel makes the structure lighter and more flexible.

The steel provides tensile strength, allowing the structure to support larger loads and resist forces like vibration.
