Abstract

An electric heating coil is used in an ordinary pint vacuum bottle to evaporate water under steady state conditions. The system is used on a platform balance; the heat of vaporization is determined from total energy input and total change of weight. Sources of error are discussed and accuracy obtainable in actual use is indicated.
