Heptane is often used as a single-component fuel to model the behavior of gasoline. Volatility is important to the cold-start performance of gasoline in an automobile. Use the Clausius–Clapeyron to determine saturation pressures (kPa and psia) from 275 K (35.3 F) to 290 K (62.3 F) and the percentage difference from the values from the NIST database. Use the NIST enthalpy of vaporization at 282.5 K and the NIST vapor pressure at 275 K for your calculations. Plot your results (P_sat vs. T_sat) and discuss.
