The coal has 50 J of potential energy and no kinetic energy. It is burned in the power plant to produce electrical energy, but only 20 J of electrical energy is produced.
Which of the following may account for this?

Some of the coal's energy was destroyed by the fire.
Some of the coal's energy was turned into other forms.
The fire was used to create the electrical energy from scratch.



Answer :

Some of the coal's energy was turned into other forms of energy.

What is conversion of energy?

According to the first law of thermodynamics, energy can neither be created nor destroyed but is converted from one form to another. We know that from the first law of thermodynamics, the energy that originally in the coal does not  vanish into thin air but undergoes a conversion.

Thus, want to find out what accounts for the energy of the coal. Thus, we could say that some of the coal's energy was turned into other forms as this is in consonance with the first la of thermodynamics.
