Answer: The fuel obtained from coal that is almost pure form of carbon is coke. Coke is a fuel with high carbon content and few impurities. It is made from destructive distillation of coal.
What is renewable and nonrenewable?
Resources are characterized as renewable or nonrenewable; a renewable resource can replenish itself at the rate it is used, while a nonrenewable resource has a limited supply. Renewable resources include timber, wind, and solar while nonrenewable resources include coal and natural gas.
What are fossil fuels How were coal and petroleum formed?
Over millions of years, heat and pressure from Earth's crust decomposed these organisms into one of the three main kinds of fuel: oil (also called petroleum), natural gas, or coal. These fuels are called fossil fuels, since they are formed from the remains of dead animals and plants.
What is coal and petroleum conservation?
Conservation is the process of using a resource in a more careful way so that it can be made to last for a longer period of time. We can conserve coal and petroleum by switching to alternative or renewable sources of energy, such as hydel power, wind energy, geothermal energy, tidal energy, etc.
Which amongst the following is used in the manufacturing of perfumes * coal tar coal gas coke kerosene?
coal tar is used in manufacturing of perfumes. Coal tar is composed of aromatic and aliphatic compounds with bad smell.
How is destructive distillation of coal is carried out name the product obtained and mention at least one use of each product?
Destructive distillation of coal is carried out by heating coal strongly to 1000°C in the absence of air. When coal is heated without air, it does not burn but breaks down to produce following by-products: (a) Coke: It is used in industries for manufacturing of steel and extraction of many metals.
What is rain fuel?
Rain Fuel makes sustainable technologies accessible by working from the ground up to create solar panels, wind turbines, and biofuel by using waste-stream and recycled materials. The Rain Fuel Studio is a hub for creative, sustainable creation.
What are nonrenewable resources?
Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
Why do some places in the United States have deposits of coal but others have deposits of petroleum and natural gas?
The reason for this is because fossil fuels are formed differently from one another. It is influenced by the types of organisms that lived in particular areas in the United States millions of years ago.
Which of the following were formed from decayed plants and animals that lived on Earth millions of years ago?
Fossil fuels formed from the decomposition of plants and animals from millions of years ago this is why they are called fossil fuels.
What are fossil fuels PDF?
Fossil fuels are energy resources derived from altered remains of living organisms buried by sediments and exposed to elevated pressures and temperatures for millions of years. They are defined non-renewable because of the long time it takes to create them.
How can renewable source of energy help in reducing pressure on petrol and diesel?
Yes, the renewable source of energy help in reducing pressure on petrol and diesel. Because the cost of the renewable sources is less compared to the petrol and diesel. They will not pollute the environment like petrol and diesel. so by using renewable source of energy we can reduce the usage of petrol and diesel.
