Abstract

This article describes a simple and inexpensive method to determine the enthalpy of vaporization of liquids by measuring vapor pressure as a function of temperature. The results for the enthalpy of vaporization are reasonable, while those for the vapor pressures are poorer. Also described is a simple and inexpensive temperature controller and an air thermostat.
