Question

Which of the following is not a reason that power plants are unable to achieve 100 percent efficiency?

A. The amount of work obtained from a process never has work needing to go into it.
B. Not all energy is converted heat from chemical reactions into useful work.
C. Heat is often a waste product.
D. Entropy increases.

Answer 1

The second law of thermodynamics can be applied to nuclear energy. In this law, it states that it is impossible to have an ideal work system for thermal energy, as some of this heat energy is lost to the environment when it is converted to different forms of energy.

The answer that is most related to this statement is B. Not all energy is converted heat from chemical reactions into useful work.

Answer 2

The answer is B. Power plants are efficient though not all heat is managed to be converted.

Answer:


`\boxed {\bf~Not~all~energy~is~converted~heat~from~chemical~reactions...}`
