Question

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?

Answer 1

Answer:

Potential energy in the coal gets transformed to electricity

Explanation:

• As when coal has burned the conversion of the energy takes place and the chemical energy in coal s converted into the electrical energy and thus heat is produced an is used to run the steam power engines.  

• So as the heat energy derived from the coal is converted to kinetic and kinetic is converted to mechanical and this mechanical is coveted to electrical energy to further run the machines thus energy is not destroyed it only transfers.

Answer 2

Answer:

Some of the potential energy in the coal is converted into heat energy.
