Randall D. Knight — The Micro/Macro Connection: Problem Exercise_30

The vibrational modes of molecular nitrogen are “frozen out” at room temperature but become active at temperatures above \(\approx 1500\text{ K}\). The temperature in the combustion chamber of a jet engine can reach \(2000\text{ K}\), so an engineering analysis of combustion requires knowing the thermal properties of materials at these temperatures. What is the expected specific heat ratio \(\gamma\) for nitrogen at \(2000\text{ K}\)?
