Which of the following statements is accurate?
PIT_PIT [208]

C. Useful energy out of a system is always less than the energy input of that system.

Explanation:

The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.

This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".

  • At every stage energy is usually lost when it is transformed from one form to another.
  • There is no machine that is 100% efficient.
  • A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
  • In system energy is usually lost as a result of heat and to overcome friction.
  • This reduces the amount of energy out of a system.
