Question

Quizplus · Accepted Answer

The ratio of the specific heat at constant pressure (Cp) to the specific heat at constant volume (Cv) for an ideal gas is denoted by γ (gamma). For a diatomic gas, γ is approximately 1.40, indicating that the gas is diatomic. Monatomic gases have a γ of approximately 1.67, while triatomic and more complex gases have γ values that are closer to 1.33 and decrease slightly with increasing complexity.
