Fossil fuels release by burning carbon dioxide and water.
imcomplete combustion
No. Fossil fuels store chemical energy. It is this chemical energy we tap by using them for fuels.
fuels are burned to release the chemical energy
chemical energy is in foods and fuels
Combustion of fuels release heat.
Fossil fuels contain chemical energy.
the energy that is in fossil fuels is chemical and radiant energy.
Fossil fuels are formed from organic matter that originally obtained its energy from the sun through photosynthesis. This organic matter stored the sun's energy in the form of chemical bonds, which is released as chemical energy when the fossil fuels are burned. So, the chemical energy in fossil fuels can be traced back to the sun's energy.
They don't have to be. Some fuels are fossil fuels, which are rapidly disappearing right now. Some examples of fossil fuels are oil, which we use for gas, and coal, which we use for heat and electricity. But fossil fuels take millions of years to make more, so we are rapidly using up the fossil fuels of the world.
Burning of fossil fuels is an oxidation reaction.
The energy stored in chemical fuels such as petrol is called chemical potential energy. This energy is released when the fuel undergoes a chemical reaction, such as combustion, which can be harnessed to do work.
Nonrenewable fossil fuels, like oil and coal, store a lot chemical energy in the bonds between its molecules. When these fossil fuels are burned, the chemical energy is released.
