Battino, Rubin; Dolson, David A.; Hall, Michael A.; Letcher, Trevor M.
Journal of Chemical Education, v84 n5 p822 May 2007
A simple and inexpensive method to determine the enthalpy of vaporization of liquids by measuring vapor pressure as a function of temperature is described. The vapor pressures measured with the stopcock cell were higher than the literature values and those measured with the sidearm rubber septum cell were both higher and lower than literature values.
