In fact, summer is the season for Valley residents to escape to Sedona and find relief in the 90-degree weather!
Based on the Aly and Lee model, the variation of the ideal gas heat capacity at constant pressure of several hydrocarbons (methane through pentanes) and non-hydrocarbons (O2, N2, H2, CO2 and H2O) as a function of temperature are presented in Figures 1 and 2, respectively.
