Question

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 less than energy input. energy output is more than energy input.

Explanation:

This is based on the second law of thermodynamics, which states that in energy transformations, some energy is always lost as unusable heat. For a power plant, the input energy (from fuel like coal, gas, or nuclear material) cannot be fully converted to electrical energy, since a portion is lost as heat to the surroundings. Thus, the usable electrical energy output will be less than the initial energy input.

Answer:

Energy output is LESS than energy input.
