Bitumen, a petroleum product, is now used in place of coal tar for surfacing roads. Carbonisation is the slow process of conversion of dead vegetation into coal. It takes millions of years for the formation of fossil fuels like coal, petroleum etc. Once exhausted it will again take long time for its formation.
(a) The slow process of conversion of dead vegetation into coal is called carbonisation. (b) Coal and petroleum are formed from the dead remains of organisms and are known as fossil fuels. (c) The black thick liquid with unpleasant smell is known as coal tar. (d) During the processing of coal to get coke, coal tar and coal gas are also obtained. (e) The process of separating the various ...
Solution. Verified by Toppr. Dead remains of plants got buried under the earth millions of years ago. Due to intense heat and pressure inside the earth they got converted into coal. The process of conversion of dead remains of plants into coal is called carbonization.
The slow process of conversion of dead vegetation into coal is called _____. A. carbonisation. B. ... And Petroleum Question 14 Plants contain mainly carbon, which gets converted into coal. Hence, the slow process of conversion of dead vegetation into coal is called carbonisation. View Solution. Olympiad Test: Coal And Petroleum Question 15 ...
Coal contains mainly carbon. The slow process of conversion of dead vegetation into coal is known as carbonization. Coal is formed from the remains of vegetation; therefore, it is also known as fossil fuel. When coal burns, it produces mainly carbon dioxide gas. When coal is processed in industry, it produces some useful products such as coke ...
What is the process called where coal is formed from dead vegetation explain how for Class 8? This process is called carbonization . So, carbonization can be defined as the slow process in which the dead plants and trees under the surface of the earth in high pressure and temperature form coal.
(a) The slow process of conversion of dead vegetation into coal is called_____. (2) Fill in the blanks. (b) Coal and petroleum are formed from the dead remains of organisms and are known as _____. (3) Fill in the blanks. (c) The black thick liquid with _____ smell is known as coal tar. (4) Fill in the blanks.
As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since it was formed from the remains of vegetation, coal is also called a fossil fuel. Question 4. Fill in the blanks : (a) Fossil fuels are Coal, Petroleum and Natural gas.
Assertion (A): The slow process of conversion of dead vegetation into coal is called catenation. Reason (R): When heated in air, coal burns and produces mainly carbon dioxide gas. ... Reason (R): They cannot be prepared in laboratory as their formation is a very slow process and conditions for their formation cannot be created in the laboratory. A)
The Slow conversion of dead vegetation into coal is called carbonisation. Yes, it is the true statement as the process of carbonization is the slow process by which the dead plants buried deep under the earth surface have become coal. Coal is usually made from the remains of dead plants and animals known as fossil fuel.
When these died, they too got covered. Sometimes earthquake and volcanoes buried entire forests deep down in the earth. The high temperature and high pressure inside the earth slowly converted the buried vegetation into coal. A coal contains mainly carbon. Thus, this slow process of conversion of wood into coal is called carbonization.
what is coal ? coal is as hard as stone and is black in color. It is one of the fuel used to cook food. it is used in railway engines to produce steam. in thermal power plants to produce electricity. it is also used as fuel. What is carbonization? slow process of conversion of dead vegetation into coal is called carbonization.
