(The better you can control the temperature, the better your heat of vaporization results will be.) Then you graph your results and you should get a straight line. Take two widely separated points on this line and plug the values into an equation I will present below, and behold!

Part I: A calorimeter, originally built to measure the heat capacities of liquids at temperatures from 100 to 400°F and at pressures up to 1000 pounds per square inch, was modified to extend its utility to include the measurement of latent heats of vaporization of liquids over the same range of conditions.

The enthalpy change upon vaporization of 1-pentene was experimentally determined by calorimetric measurements at temperatures between 100 [degrees] and 280 [degrees] F. The results are in good agreement...

The accuracy of empirical force fields is inherently related to the quality of the target data used for optimization of the model. ... With the heat of vaporization (ΔHvap) of N-methylacetamide (NMA), a range of values has been reported as target data for optimization of the nonbond parameters associated with the peptide...
