Graph the data.
Describe the relationship between the variables (Temp and Vapor Pressure).
Do necessary manipulations to quantify the relationship between the variables and calculate the enthalpy of vaporization.
Draw a structural formula for each molecule, describe the IMFs that molecule exhibits, and draw a connection between the structure and its enthalpy of vaporization.
