  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nylon is a synthetic thermoplastic linear polyamide-based polymer. 


It is used for a variety of applications to include clothing, reinforcement in rubber material like car tires, for use as a rope or thread, and for a number of injection molded parts for vehicles and mechanical equipment. 


It is exceptionally strong, relatively resistant to abrasions and moisture absorptivity, long-lasting, resistant to chemicals, elastic and easy to wash. 

It is the plastic of choice for components in the engine compartment of vehicles because of its high tensile strength, temperature resilience, and chemical compatibility.

Therefore, option A is correct.

State whether true or false :

Ropes made by rayon are used in cranes and elevators.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Rayon is a manufactured fiber made from regenerated cellulose fiber. 

It is made from purified cellulose, primarily from wood pulp, which is chemically converted into a soluble compound. 

Because rayon is manufactured from naturally occurring polymers, it is considered a semisynthetic fiber and the strength is not enough that can withstand high stress to be used in cranes and elevators like metal ropes.

Therefore, option B is correct
Multiple choice chemistry substances in daily use polyester and acrylic rayon and nylon synthetic fibres

Ropes made of _______ are used in cranes and lifts.

  1. rayon

  2. nylon

  3. acrylic

  4. spandex
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nylon ropes are used in cranes and lifts because of high tensile strength and elasticity of nylon.


Nylon is the strongest of all ropes in common use. It is used for absorbing shock loads, such as when lifting or towing because it has the ability to return to it's original length after being stretched. 

It also has good abrasion resistance and can last several times longer than natural fibres.

Therefore, option B is correct.

Multiple choice chemistry substances in daily use polyester and acrylic rayon and nylon synthetic fibres

Name the plastic whose sheets are used for packing liquids.

  1. Polythene

  2. Polycot

  3. Polywool

  4. Polyester
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
In order to pack the liquids, Polyethylene terepthalate is used.

It is an important substance that can store the liquid without leakage.

It is a polymer of ethylene terepthalate and is quite durable in carrying the stuff from one place to another.

Strength and durability are the two important factors that make it an important choice.

Hence, the correct option is $\text{A}$
