For a diatomic ideal gas, which of the following options is/are correct?
- gamma = 1.40
- C_P = 7R/2
- C_V = 5R/2
- gamma = 1.67
Correct answer: C_V = 5R/2
Solution
For a diatomic gas with 5 degrees of freedom: C_V = 5R/2, C_P = 7R/2, and gamma = C_P/C_V = 1.40. The value gamma = 1.67 corresponds to a monoatomic gas.
