as far as i know its because some fuels are atomically more dense than others, also because the technology we have may not burn some fuels as efficiently as others
When chemicals burn and it sometimes release ashes and the fuel is converted to heat and light energy
Fossil fuels contain the chemical energy that plants and algae obtained from sunlight and then stored in sugars. Just as energy chemical energy is stored in sugars, chemical energy is stored in fossil fuels. All it takes to release it is enough heat and oxygen to cause the fuel to burn.
When you burn it, the chemical energy is converted to thermal energy.
People burn fossil fuels to get the energy stores in then the energy then causes the engines to run.Help to cook food.Help to light the surroundings.
The chemical potential energy in fossil fuels is converted to thermal energy (heat) by burning them.
Yes, heat.
Energy is a key resource. We burn fuels to get energy. Sometimes it is also done by the environment itself.
Fuels
We burn them

Energy led human to burn more fossil fuels
Burn it

If you are trying to lose weight, no you should expend more of your muscle energy. Otherwise, yes. Additional energy expenditures force us to burn fossil fuels.
