In p vs. (1/T) were obtained for the coverages x of 1.25, 1.50, and 1.75 monolayers and there is an indication of a phase transition at about 19K, which agrees with the results of specific heat data on the same system. The molar entropy and internal energy were computed as a function of coverage. Is
Vapor pressure measurements of 4He adsorbed on Grafoil for coverages x = O. 94 and 1.00 were made as a function of temperature in the temperature range of 5-10 K. The data are presented as plots of In p vs. 1/T and from these dp/dT vs. T curves are presented. For both coverages there is an indicatio
