The source of raw material for plastic industry isa)chemicals.b)polyme...

It is a by-product of petroleum received after petroleum refining. Oil and natural gas are the major raw materials used to manufacture plastics. The plastics production process often begins by treating components of crude oil or natural gas in a "cracking process." This process results in the conversion of these components into hydrocarbon monomers such as ethylene and propylene.

The source of raw material for plastic industry isa)chemicals.b)polyme...

The source of raw material for the plastic industry is polymers. Let's understand this in detail:

Explanation:
Plastics are made from polymers, which are large molecules made up of repeating units of smaller molecules called monomers. These monomers can be derived from natural sources like cellulose (found in plants) or from synthetic sources like petroleum.

Polymerization:
The process of combining monomers to form polymers is called polymerization. There are two types of polymerization: addition polymerization and condensation polymerization.

- Addition polymerization: In this process, monomers are added together to form a polymer without the elimination of any by-products. For example, polyethylene is made by combining ethylene monomers.

- Condensation polymerization: In this process, monomers react with each other to form a polymer and a small molecule like water is eliminated as a by-product. For example, nylon is made by combining hexamethylenediamine and adipic acid.

Types of Polymers:
There are two types of polymers used in the plastic industry:

- Thermoplastics: These are polymers that can be melted and re-molded multiple times without losing their properties. Examples include polyethylene, polypropylene, and polystyrene.

- Thermosetting plastics: These are polymers that undergo a chemical reaction during the curing process and become rigid and cannot be melted or re-molded. Examples include epoxies and phenolics.

Conclusion:
Thus, polymers derived from natural or synthetic sources are the raw materials used in the plastic industry for the production of various plastic products. The type of polymer used depends on the properties required for the end product.

Read the case study given below and answer the questions that follow:Cotton textile industry has three sub-sectors i.e. handloom, power loom and mill sectors. Handloom sector is labour-intensive and provides employment to semi-skilled workers. It requires small capital investment. The power loom sector introduces machines and becomes less labour intensive and the volume of production increases. Cotton textile mill sector is highly capital intensive and produces fine clothes in bulk.Cotton textile manufacturing requires good quality cotton as raw material. India, China, U.S.A, Pakistan, Uzbekistan, Egypt produces more than half of the world’s raw cotton. The U.K, NW European countries and Japan also produce cotton textile made from imported yarn. Europe alone accounts for nearly half of the world’s cotton imports. The industry has to face very stiff competition with synthetic fibres hence it has now shown a declining trend in many countries. With the scientific advancement and technological improvements, the structure of industries changes. For example, Germany recorded constant growth in the cotton textile industry from the Second World War till the seventies but now it has declined. It has shifted to less developed countries where labour costs are low.Q. Why has the cotton textile industry shifted to less developed countries?

Directions: Read the following passage very carefully and answer the questions on the basis of it:Iron and steel Industry The Iron and steel industry forms the base of all other industries and, therefore, it is called a basic industry. It is basic because it provides raw material for other industries such as machine tools used for further production. It may also be called a heavy industry because it uses large quantities of bulky raw materials and its products are also heavy.Iron is extracted from iron ore by smelting in a blast furnace with carbon (cok e) and limestone. The molten iron is cooled and moulded to form pig iron which is used for converting into steel by adding strengthening materials like manganese. The large integrated steel industry is traditionally located close to the sources of raw materials - iron ore, coal, manganese and limestone - or at places where these could be easily brought, e.g. near ports. But in mini steel mills access to market is more important than inputs. These are less expensive to build and operate and can be located near markets because of the abundance of scrap metal, which is the main input. Traditionally, most of the steel was produced at large integrated plants, but mini mills are limited to just one-step process – steel making-and are gaining ground.Distribution: The industry is one of the most complex and capital-intensive industries and is concentrated in the advanced countries of North America, Europe and Asia. In U.S.A, most of the production comes from the north Appalachian region (Pittsburgh), Great Lake region (Chicago-Gary, Erie, Cleveland, Lorain, Buffalo and Duluth) and the Atlantic Coast (Sparrows point and Morisville). The industry has also moved towards thesouthern state of Alabama. Pittsburg area is now losing ground. It has now become the “rust bowl” of U.S.A. In Europe, U.K., Germany, France, Belgium, Luxembourg, the Netherlands and Russia are the leading producer’s.The important steel centres are Scun Thorpe, Port Talbot, Birmingham and Sheffield in the U.K; Duisburg, Dortmund, Dusseldorf and Essen in Germany; Le Creusot arid st. Ettienne in France; and Moscow, St.Petersburgh, Lipetsk, Tula, in Russia and Krivoi Rog and Donetsk in Ukraine. In Asia, the important centres include Nagasaki and Tokyo-Yokohama in Japan; Shanghai, Tienstin and Wuhan in China; and Jamshedpur, Kulti-Bumpur, Durgapur, Rourkela, Bhilai, Bokaro, Salem, Visakhapatnam and Bhadravati in India.Q.
