Question

Choose the following substance which is made up of thermosetting plastic.

  1. Pen
  2. Shoes
  3. Crockery
  4. Handbag

hintHint:

Thermoplastics can be heated and shaped over and over again while thermosetting plastics can only be heated and shaped once.

The correct answer is: Crockery


    • Melamine is a thermosetting polymer. This is a hard, highly polished polymer used to make unbreakable kitchen utensils.
    • Thermosetting resins are used for pot handles because they do not soften when heated and do not bend easily. These plastics, like Bakelite, have poor thermal conductivity. Thermosets are used in electrical plugs/switches/headers due to their poor electrical conductivity.

    Melamine is used in Crockery.

    The plant fibers' basic component is

    The correct option is b)cellulose.
    One of the most abundant biomaterials on earth IS Cellulose. Usually synthesized by plants, but also produced by some bacteria. Like starch, cellulose is a homopolymer of glucose, but unlike starch, the glucose monomers are held together by β-1,4 linkages.

    Select a synthetic fiber from the following.

    The correct option is a)Rayon.
    Synthetic fibers are man-made fibers, most of which are made from petroleum, called petrochemicals. Rayon is a regenerated cellulose fiber, commonly derived from wood pulp. Rayon is usually made from the eucalyptus tree, but any plant can be used (bamboo, soybean, cotton, etc.).

    _____ fiber is made of a natural polymer called cellulose.

    The correct option is c)Cotton.
    As cotton is made up of long chains of glucose molecules, it is naturally found in plants and is made up of pure cellulose, a naturally occurring polymer. Cellulose is actually a naturally occurring polymer. It is mainly obtained from plant wood and its derivatives such as grasses, aquatic plants. Cellulose helps plants stay firm and tough and is an important source of dietary fiber.

    Select the correct characteristics of plastics.

    The correct option is d)All of the above.
    Plastics, like synthetic fibers, are polymers that, while flexible, can be molded into desired shapes and sizes and cured to create durable objects. The term "plastic" is derived from the Greek word "plastikos" meaning "to form" and is used to refer to a wide range of semi-synthetic polymers.
    Properties of plastic:

    • They are light and chemically stable.
    • It can be easily molded into different shapes and sizes.
    • Excellent heat insulation and low thermal conductivity.
    • It has excellent impact resistance and does not rust.
    • Excellent transparency and abrasion resistance.
    • Poor dimensional stability and easy to deform.
    • processing cost is low.

    State true or false: Silk fiber is obtained from the cocoon of a silkworm.

    The statement is true.
    The cocoons are collected and stored in the sun or boiled or steamed. This helps separate the silk fibers. The process of separating the silk thread from the cocoon is called silk winding. The silk fibers are then spun into yarn. The resulting silk thread is woven into the desired garment.
    Sericulture has two steps:

    • Care of silkworms from the egg stage to the completion of the cocoon.
    • Production of mulberry trees that provide leaves for earthworms to feed on.

    Select a biodegradable material from the following.

    The correct option is d)Paper.

    • "Biodegradability" refers to the ability of a substance to break down (break down) biologically (with or without oxygen) by the action of microorganisms such as bacteria and fungi while being absorbed into the natural environment.
    • No ecological damage occurs during the process.
    • Paper is biodegradable because it is made from plants, and most plant materials are biodegradable.
    • Paper is easily recycled and is considered more environmentally friendly than plastic as it can be recycled 6-7 times before its fibers are too short to be used in papermaking.

    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.
