Which of the following statements is incorrect?
(A) The carnot cycle is not specifically meant for gases and can always be applied to mechanical or electromagnetic systems so long as the thermodynamic processes have proper analogs.
(B) The Carnot cycle can be carried out for nonthermodynamic systems such as those involving paramagnetic substances and surface films.
(C) An ideal Carnot cycle has \( 100 \% \) efficiency.
(D) The efficiency of a Carnot cycle is independent of the working substance employed because all reversible engines are necessarily less efficient than the Carnot heat engine.
