For an ideal gas, Cp - Cv is____________________?
Correct answer: A. R
- A. R
- B. -R
- C. 0
- D. (3/2) R
Explanation
For an ideal gas, the Mayer relation gives Cp - Cv = R, where R is the universal or specific gas constant as appropriate. This relation follows because an ideal gas has no intermolecular potential-energy contribution.
