Question

choose the correct answer. during every energy transformation, some energy is lost as heat. how does this affect the amount of electrical energy made by a power plant? energy output is more than energy input. energy output is less than energy input.

Explanation:

According to the law of conservation of energy, energy cannot be created or destroyed, only transformed. In a power plant, during energy transformation (e.g., from chemical energy in fuel to electrical energy), some energy is lost as heat (due to inefficiencies like friction in machinery, resistance in electrical components etc.). So the electrical energy (output) obtained is less than the initial energy (input, like the energy content of the fuel).

Answer:

Energy output is LESS than energy input.
