Before burning, coal holds potential energy, while after burning, it transforms into heat energy and powers electricity generation. The characteristics of energy in the embers relate to blackbody radiation and energy transfer.
Energy Before: In the coal, the energy exists as potential energy stored within the coal. This potential energy is released through combustion when the coal burns, transforming into heat energy.
Energy After: After burning, the coal's energy is now in the form of heat energy, which can be used to boil water and create steam, spinning turbines to generate electricity.
Blackbodies and Energy Transfer: The glowing embers in the fireplace exhibit characteristics of blackbodies, emitting radiation due to their high temperature.
