Summer is a great time to visit Sedona because the weather is warm but not nearly as hot as the infamous triple-digit days typical for Phoenix, Scottsdale and the rest of the Valley of the Sun. 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.
The symbol for the Universal Gas Constant is Ru= 8.314 J/mol.K (0.0831 bar dm3 mol-1 K-1). The Specific-Heat Capacity, C, is defined as the amount of heat required to raise the temperature by 1K per mole or per kg.The Specific Heat Capacity is measured and reported at constant pressure (Cp) or constant volume (Cv) conditions. For monoatomic gases Cp=2.5Ru J/mol.K and Cv=1.5Ru J/mol.K repectively.The ratio of the two specific heats is called the adiabatic ratio of the gas.t temperature t the heat content of water vapor is: hw = 2501 + 1.84 t. Notice that water vapor, once generated, also requires more heat than dry air to raise its temperature further: 1.84 kJ/kg.C against about 1 k J/kg.C for dry air.
