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.
At atmospheric pressure (0 bar g), water boils at 100Â°C, and 419 kJ of energy are required to heat 1 kg of water from 0Â°C to its boiling temperature of 100Â°C. It is from these figures that the value for the specific heat capacity of water (Cp) of 4.19 kJ/kg Â°C is derived for most calculations between 0Â°C and 100Â°C.
