NCERT Solutions for Class 8 Science Chapter 3: Points to Remember

Some of the important points of NCERT Class 8 Science chapter 3 are mentioned below to help you score the best marks in the exams.

  • Polymer:
    (i) Monomer: The simplest chemical molecule in a chain of the polymer.
    (ii) Polymer: The product formed by the combination of a large number of monomers in a straight or crossed chain.
    (iii) Polymerisation: The process of combining monomers to form polymers under suitable physical and chemical conditions.
  • Types of Synthetic Fibres:
    (i) Rayon or Artificial silk: A regenerated cotton fibre manufactured by using chemical methods, which is as smooth as silk.
    (ii) Rayon fibre is used in making bedsheets. On blending with wool, it is used for making carpets. Long filaments of it are used in making reinforced automobile tyres.
    (iii) Nylon: A superior synthetic fibre made by the polymerisation of amide molecules obtained from petroleum products.
    (iv) Polyester (Polyethene Tetraphthalate): A plastic material prepared by the polymerisation of ethene-tetraphthalate.
    (v) Polyester is used for making crease resistant clothes, food packaging containers and magnetic tapes used in audio and video cassette recorders.
    (vi) Terylene / Dacron: A synthetic fibre obtained by polymerising molecules of terephthalic acid and ethylene glycol.
  •  Plastics:
    (i) Plastic: A material which can be easily moulded into various forms.
    (ii) Plasticity: The property of a material due to which it can be moulded into various forms.
    (iii) Polythene: A plastic material prepared by the polymerisation of ethene gas.
    (iv) Polythene is used for making films for carry bags, adhesive tapes, etc. It is also used in making kitchen and laboratory ware, insulation of electric wires and as an anti-corrosion coating on articles made from iron.

FAQs on NCERT Solutions for Class 8 Science Chapter 3

Q.1: From where can I download the Class 8 Science chapter 3 NCERT Solutions?

Ans: Students can download the Class 8 Science chapter 3 NCERT solutions from this page with the help of the link provided.

Q.2: What is the name of the CBSE Class 8 Science chapter 3?

Ans: The CBSE Class 8 Science chapter 3 is Synthetics Fibres and Plastics.

Q.3: Explain the difference between thermoplastic and thermosetting plastics.

Ans: The difference between thermosetting plastics and thermoplastics are:
Thermosetting plastics cannot be bent, whereas thermoplastics can be bent easily. Upon heating, thermosetting plastics do not soften. Hence they cannot be reshaped once they are moulded. On the other hand, thermoplastics soften easily upon heating and can be reshaped easily.
