What Types of Natural Resources are Coal and Petroleum

1. What Types of Natural Resources are Coal and Petroleum? Definition, types and Example Fuels such as Coal and petroleum form very deeply below the Earth's surface under high temperature and high-pressure conditions for a very long period. Under these conditions, fossilized organic matter undergoes chemical conversion to form Coal on land and Petroleum underwater. Petroleum and Coal fall in the category of fossil fuels because they are formed from the preserved remains of organisms that lived millions of years ago, and people use them as fossil fuels. Fuels like Petroleum and Coal have been beneath the Earth's surface for

2. a long time. CBSE has added a whole chapter in the Class 8 Science Syllabus to make students aware of fossil fuels. Coal: Coal is a combustive black or brownish-black sedimentary rock rich in carbon and hydrocarbons. Coal is categorized as a non-renewable energy source because it takes millions of years to form. Coal includes the stored energy of plants that lived in wetland forests hundreds of millions of years ago. What are the uses of Coal? Coal seems to be one of the cheapest and essential sources of energy. Here is the list of some practical uses of Coal. Domestic Use (Cooking food or Room Heating) Electricity Generation Production of Steel As fuel for different types of Industries Gasification and Liquefaction ■ ■ ■ ■ ■ Types of Coal: Coal is a black diamond and is classified mainly into four categories. Those are: 1. Anthracite Coal: Anthracite is the purest form and highest rank of Coal. It is a complex, brittle, black shiny coal, often called hard Coal, holding a high percentage of designated carbon and a lower portion of volatile matter. Anthracite coal is used for heating homes and in gas production. 2. Bituminous Coal Soft charcoal that burns with a smoky yellow flame. Bituminous Coal is the most common form of Coal. It has a high sulfur content, and when burned, it releases

3. sulfur-containing compounds, causing air pollution and acid rain. Bituminous Coal is used for Smithing Coal, power generation, and Coking Coal. 3. Subbituminous Coal Sub-bituminous Coal is a type of Coal with characteristics ranging from lignite to bituminous Coal, and we mainly use it as a fuel for steam power generation. Sub Bituminous coals are dull at the lower end of the range, dark brown to black, soft and brittle, and light black at the upper limit, complex, and can be relatively strong. Subbituminous Coal is only used for generating electricity and can be used to produce petroleum gas. 4. Lignite Coal Lignite, also called lignite, has the lowest carbon concentration. Lignite has a low calorific value and a high water content and is mainly used for power generation. To study "Coal and Petroleum," you can check out NCERT Solution for Class 8 Science. Petroleum: Petroleum means "the rock oil" The meaning of Petroleum is derived from the Greek word "petra" and "Oleum," a Latin word. Petroleum is a naturally occurring liquid in rock formations. It is composed of a complex mixture of hydrocarbons of different molecular weights and other organic compounds. Some compounds derived from Petroleum are also derived from other fossil fuels. Petroleum has an enormous impact on human life. It's referred to as "Black Gold." Petrochemicals are produced from Petroleum. Petrochemicals are produced in only a few places in the world. Petroleum is used as raw material for many industries such as pharmaceuticals, fertilizers, pesticides, solvents, plastics, and synthetic fragrances.

4. Products of Petroleum: Petroleum products are produced by crude oil in oil refineries. According to a study, the by-product of Petroleum provides a scope to produce 6000+ products. For example, fertilizers, pharmaceuticals, and many more. Below is the list of a few essential petroleum products. Gasoline Petrol Oil Diesel Oil Tar Heavy Fuel Oil Lubricant Paraffin Wax Petroleum Coke Aviation Gasoline ■ ■ ■ ■ ■ ■ ■ ■ ■ Uses of Petroleum: In today's world, Petroleum is one of the most important and widely used fuels. Some of its advantages are: In all means of transportation like road, air, water, and rail, we significantly use Petroleum as a fuel. Diesel is used as fuel in electricity generation plants to run the turbines. Petroleum Oil is used to generate electricity through generators at home or offices. We use kerosene oil for various home purposes— cooking, lighting, and Heating. Petrochemicals are produced from Petroleum. Petrochemicals are used to produce more than a thousand products that we use in our daily lives, including plastic, medicine, cosmetics, furniture, appliances, electronics, solar power, and many more. ■ ■ ■ ■ ■ FAQ: Q. Which petroleum product do we use as a fuel?

5. Ans. Kerosene. Kerosene is a petroleum product used as fuel for lamps, stoves, and aircraft. Q. What is Petroleum? Ans. We extract Petroleum as crude oil from Earth, a fossil fuel. Like Coal and Natural Gas, Petroleum is formed from the remains of orgasms such as old sea creatures, plants, algae, and bacteria. Q. What is fossil fuel? Ans. Fossil fuels are fuels produced by decomposing dead organisms buried under the pressure and heat of the Earth's crust. It takes millions of years for organic matter to chemically change to form fuel—natural processes continuously from fossil fuels. Q. Where can I download the class 8 worksheet? Ans. A worksheet is a good tool for effective learning. It engages students to ensure active learning. You can download the Worksheets for Class 8 from the official website of Physics Wallah.
