The value of Cp & Cv respectively for monatomic gases in Kcal/kg Mole.°K are________________?
Correct answer: A. 5 & 3
- A. 5 & 3
- B. 3.987 & 1.987
- C. 1.987 & 0.66
- D. 0.66 & 1.987
Explanation
For a monatomic ideal gas, Cv = 3R/2 and Cp = 5R/2. Using R ≈ 1.987 kcal/(kg mol·K) gives approximately Cp = 5 and Cv = 3, so option a uses rounded values.
