Companies are burning coal through combustion to produce electricity. The amount of electrical energy produced is less than the amount of stored potential energy found in coal. Which best explains this observation?
A) There is no way to know the amount of energy in coal
B) Some of the potential energy in the coal is converted into heat energy.
C) As turbines and generators in the power plant convert potential energy to kinetic, some of the energy is lost.
D) Due to the intense heat during combustion, some some potential energy is destroyed before being converted to kinetic energy.
