Question

Example of non-biodegradable material is…………..
(a) Fruits
(b) Vegetables
(c) Paper
(d) Polythene

Answer 1

Hint: They are made from nonpolar saturated hydrocarbons with very high molecular weights. Ethylene is the primary constituent of it. They usually have a waxy texture. They are formed from nonpolar saturated hydrocarbons with very high molecular weights.

Complete answer:
A Non-Biodegradable material is often defined as a sort of substance that can't be weakened by natural organisms and acts as a source of pollution. They continue to be on earth for thousands of years with no degradation.
Polythene is an example of non-biodegradable. Polythene usually has a linear structure and is known to be additional polymers. The first application of those synthetic polymers is in packaging. Polythene usually wants to make plastic bags, bottles, plastic films, containers, and geomembranes. It is often noted that over 100 million tonnes of polyethylene are produced on an annual basis for commercial and industrial purposes. The overall formula of polyethylene is often written as similar to ethene. Most sorts of Polythene are thermoplastic (they are often remolded by heating). However, some modified polyethylene plastics exhibit thermosetting properties. An example of such a category of polyethylene is cross-linked polyethylene (often abbreviated to PEX).

Additional information:
This is often believed to be the rationale why the chemical properties exhibited by Polythene are sort of almost like those of paraffin. It is often noted that the individual polyethylene macromolecules aren't linked via covalent bonds. However, these molecules crystallize because of their rather symmetric molecular structures. Therefore, polythene is often considered as fractionally crystalline plastic. The higher the crystallinity of the polymer, the higher its density and chemical stability. Polythene is the commonest plastic used broadly within the packaging industry. Supporting the density, polythene is often classified into two types: Low-density polythene and High-density polythene.
Uses of Polythene
- Polythene having lower density, has the power to deform without breaking and better gives elongation with stretching up to 6 times the length before breaking.
- It is a useful plastic for molding and extruding in various shapes like bottles, sheets, and pipes, etc.
- It is employed for plastic bags, stretch films due to its clear and crystalline nature.
- The life expectancy of those in outside conditions is found to be 25 years but degrades from ultraviolet.
- Polythene has greater chemical resistance which covers a good range of chemicals.

So, the right answer is 'Polythene'.

Note:
Polyethylene, also referred to as polythene or polyethylene, is one of the foremost commonly used plastics within the world. The first uses of polythene are in packaging film, garbage bags, grocery bags, insulation for wires and cables, agricultural mulch, bottles, toys, and housewares. Polythene is additionally utilized in trays, fruit crush containers, milk containers, crates, and food packaging products.
