Holly Schwartz · Answer 1

Answer: Burn the Coal

Explanation:

Kinetic energy is the energy of motion. Sometimes, this motion is internal. When coal is heated, the atoms and molecules inside of the coal can gain a large amount of kinetic energy. This is experienced as heat. The best way to release all of a chunk of coal's internal kinetic energy is to burn it.

Marisol · Answer 2

A. burn the coal

Explanation:

Burning the coal is only the way to convert the stored chemical energy of the coal into the the kinetic energy of its molecules that can then be transferred to the nearby objects in the form of heat by the various modes of heat transfer such as conduction, convection or radiation.

Conduction is the contact method of heat transfer in which the adjacent atom transfers the vibration kinetic energy.

Convection is the bulk mode of heat transfer in which the bulk mass of molecules moves near and far to the heat source.

Radiation is the distant mode of heat transfer in the form of electromagnetic waves.
