Question

What type of energy is released when fossil fuels are burned?
a.
electrical energy
b.
nuclear energy
c.
kinetic energy
d.
chemical energy

Answer 1

Hello @mayberyv !
What do you think it should be ?

Answer 2

Can you eliminate any of the options ?

Answer 3

i think the most probable answer for this is d because when fuel is burned it reaches the activation point which initiates chemical rxn .is i think it is d

Answer 4

That's correct

Answer 5

sorry it took so long i think its chemical cause of the fact that it is fossils so its like a chemical reaction

Answer 6

he answer is implicit in the question, in that "heat" energy is released when something burns, however, the answer you're looking for may be "what sort of energy does fossil fuel contain?", and that is called Chemical Potential Energy (CPE). There is a certain amount of Energy available that is stored as chemical energy and not used until the correct conditions exist (heat, prescence of oxygen and source of ignition). Once the CPE is released, the energy becomes an expanding cloud of hot residual gases possessing properties known as Heat Energy & Kinetic Energy (kinetic is something that moves) that can cause other things to move, such as a piston in a car's engine.

Answer 7

thanks pal

Answer 8

I think it's not implicit. The question asks you that what kind of energy is `Released`. It's the chemical potential energy (which was stored in the chemical bonds of fossil fuel) which is released in the form of heat energy
