What is plastics?

Answer 1

The word 'plastics' is a general term for artificially made substances which can be moulded and squeeezed and pressed into various shapes, generally after they have been heated. When they cool, they set in the required shape. Different plastics have different properties. Some are hard when set, others flexible. Some can't be softened with heat, others can (these are known as thermoplastics).

Answer 2

Plastic is made of monomers

Organic plastics are polymers, composed of monomers (repeating units). A polymer is a chain of molecules repeated again and again

these monomers will become plastic by addition polymerisation and the monomers are held by weak intramolecular forces and the forces may align themselves in a linear chain or a simple branched chain

Answer 3

Plastics are synthetic materials made from polymers, which are long chains of molecules. They are versatile, lightweight, and can be molded into various shapes, making them widely used in manufacturing and packaging. However, plastics pose environmental challenges due to their persistence in the environment and issues with disposal and recycling.

Answer 4

is when a solid has the ability to flow as a liquid

Plasticity of the inner earth is the reason for Continental Drift

Answer 5

It was discovered in 1956 by scientist Weston Rivett of Sembach, Germany. Made from crude oil and coal, it has many uses in medical and dental applications.

Answer 6

A plastic can be defined as a synthetic material made up of a wide range of polymers.
