Define the following (a) Polymer (b) Synthetic fibre
Answers
Answer:
polymer) A polymer is a very big molecule formed by the combination of a large number of small molecules . The small molecules which join together to form a polymer is called monomer . The monomer which make a polymer may be of the same compound or of different compound
synthetic fibre) Synthetic fibres are made by humans through chemical synthesis, as opposed to natural fibres that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occuring animal and plant fibres

Answer:
The definitions of the given topics are given below:
(a) A polymer is any of a category of natural or synthetic substances composed of very large molecules, called macro molecules, which are multiples of simpler chemical units called monomers.
(b) Synthetic fibers are artificial fibers, most of which are made from petroleum raw materials known as petrochemicals. All fabrics come from fibers, but fibers come from artificial sources.
Explanation:
Polymers:
Polymers structure many of the materials in living organisms and are the basis of many minerals and man-made materials. The word polymer refers to an unspecified number of monomer units. When the amount of monomers is very large, the compound is usually called a high polymer. Polymers aren't restricted to monomers of the same chemical composition or molecular weight and structure. Some natural polymers are composed of 1 kind of monomer.
Synthetic Fibers:
They are composed of small units or polymers composed of many repeating units known as monomers. These include nylon, acrylic, polyurethane, and polypropylene. Millions of tonnes of these fibers are produced worldwide each year.
