examine the enthalpy of vaporization for multiple solvents such as 2-proponal and methanol. This part of the experiment required us to take many recordings of the temperature changes of the solvents in order to get the DT values for the solvents. By determining the DT values we can effectively rate the solvents in order of the strength of their intermolecular forces. In the second part of the experiment we constructed a micro-gauge in order to determine the triple point of Carbon Dioxide. This part of the experiment was challenging in that it required very keen and close observations to notice exactly when liquid Carbon Dioxide was first present.
