Question

Name three fossil fuels and name three non- fossil fuels and what energy conservation is happening when charcoal is used as fuel for barbeque?

Answer 1

Hint: We will start answering this question by first stating what is fuel, then we will talk about fossil fuels. And at last we will name a few fossil fuels and few non-fossil fuels. Later we will talk about what is energy conservation and what happens when charcoal is used as fuel for barbeque.

Complete answer:
Lets see what fossil fuels are: Any material that may be made to react with other substances to release energy as thermal energy or to be used for work is referred to as a fuel.Now let's talk about fossil fuels in brief: A fossil fuel is a fuel that is created by natural processes, such as anaerobic decomposition of buried dead creatures, and contains organic molecules that were formed during ancient photosynthesis and release energy when burned. Hence they are good as they are a cheap source of energy and reliable.
Examples of Fossil fuels are: Coal, oil, and natural gas
Non-fossil fuels: Solar, wind and hydro.

Now\[C + {O_2} \to {\text{ }}C{O_2}\] lets see what is conservation of energy: Conservation of energy is a physical principle that states that the energy in a closed system remains constant. Charcoal is made from wood that has been burned in a low-oxygen environment to remove water and other contaminants (methane, hydrogen, etc.).

Carbon is pretty much all that's left. As a result, when you make charcoal, you're releasing energy through reactions like \[2{H_2} + {O_2} \to {\text{ }}2{H_2}O\]. Because the total energy associated with bonding in H2O is lower than in the reactants, the energy is liberated. You release energy when you take charcoal and burn it in a Barbeque.

Note:Many students think that coal is not a fossil fuel. Confusion lies between coal and charcoal. Remember that coal is a fossil fuel, but charcoal on the other hand is not a fossil fuel. This is because charcoal is made from burning wood and not any fossil.
