Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since most of these substances were organic in nature, their decomposition led to large reserves of coal that we find today.
The slow process of conversion of dead vegetation into coal is called carbonisation. Question 9. What name is given to the process of heating a substance in absence of air ? Answer: Destructive Distillation. Question 10. How is coke obtained ? Answer: Coke is obtained by heating coal in the absence of air. Question 11. How is coal tar formed ...
Due to high pressure and temperature and the absence of air, the wood of the buried forest plants and trees slowly got converted into coal. The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel.

Coal gas is obtained during the processing of coal to get coke. E.) Petroleum gas is in liquid form. F.) The world's first oil well was drilled in Pennsylvania. 2.)
The temperature also rose as they sank deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. 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.
The slow process of conversion of dead vegetation into coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil formation of coaloccurs over millions of years. In thisprocess, dead vegetation is converted into carbonrich coal under very high temperature and pressure.
and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation.
