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 exponential behavior of vapor pressure as a function of temperature, P(T), is given by the exponential function: (1). A in the expression is an experimental constant that can be related to the normal boiling point, (HVap is the heat of vaporization of the liquid and R is the gas constant, R = 8.314 J/(K mol).his week in lab you will fit a set of vapor pressure vs. temperature data to the Clausius-Clapeyron equation to determine the heat of vaporization of an unknown liquid, shown in Figure 4. Figure 4. The linear relationship between ln(P) vs 1/T comes from the Clausius-Clapyeron equation.
