Answer 2

Hello mate!❤

Fuels :

A substance that can be used to produce heat at a reasonable cost is called a fuel.

Fossil Fuels :

Fuels formed from the dead remains of plants and animals,which remained buried deep under the Earth for millions of years.

Coal:

It is a hard,black or brownish-black sedimentary rock containing more than 50% of carbon by weight.It also contains hydrogen,oxygen,nitrogen,sulphur e.t.c

Crude Oil:

It is a mixture of several solid,liquid and gaseous hydrocarbons mixed with water,salt and crude particles.

Petroleum:

It is dark,viscous,oily,strong smelling and known as black gold fossil fuel.

Natural Gas:

It is very important fossil fuel,which mainly consists of methane and occurs deep under the crust of the Earth either alone or along with crude oil.It is stored under high pressure and hence called CNG
