Answers
Answer:
Step-by-step explanation:
The advantages of using CNG and LPG as fuels are as follows:
They both are cleanest burning fuels of all fossil fuels.
They are less polluting, non-corrosive.
They can be sent through pipes easily.
These are easily available and have affordable cost.
LPG and CNG both are easy to store and transport.
As there calorific value is very high therefore, they are used for cooking purpose.
The petroleum product used for surfacing roads is Bitumen.
About 300 million years ago when the earth had dense forests in low lying wetland areas.
Due to natural processes, like flooding, these forests got buried under the soil. As more soil deposited over them, they got compressed.
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.
