Question

what is the overall energy transformation in a coal - fired power plant?
electrical to chemical
chemical to electrical
nuclear to radiant
radiant to nuclear

Explanation:

In a coal - fired power plant, coal contains chemical energy (stored in the bonds of its molecules). Through combustion and subsequent processes, this chemical energy is converted into electrical energy that can be used to power homes, industries, etc. The option "electrical to chemical" is incorrect as power plants generate electricity, not consume it to store chemical energy. "Nuclear to radiant" and "radiant to nuclear" are not related to coal - fired power plants as coal - fired plants do not involve nuclear energy.

Answer:

B. chemical to electrical
