The equation, Cp - Cv = R, is true for _______________ gas?
Correct answer: C. Only ideal
- A. No
- B. Any real
- C. Only ideal
- D. Both B. and C.
Explanation
For an ideal gas, the equation of state gives Cp − Cv = R per mole, independent of the gas temperature or pressure. Real gases generally have an additional departure from this relation.
