The Vapor Pressures of Certain Hydrated Metal Sulfates

Abstract

Carbon produced by the explosion of graphitic acid showed a density of 2.215, and is, therefore, probably graphite.4. Samples of the graphites originally showed no "drift" or increase in weight with time after immersion in the liquid. The natural graphites, however, after being swelled, or increased in volume by treatment with fuming nitric acid and heat, displayed remarkable drifts. Pressure was used to hasten completion of the drift.5. The tendency to drift was largely destroyed by a severe compression of the swelled material previous to the density determination.

Determination of melanterite-rozenite and chalcanthite-bonattite equilibria by humidity measurements at 0.1 MPa

“…Results of this study at higher temperatures are also in good agreement with the measured values of Carpenter and Jette (1923;squares), and the predicted values of Malinin et al (1977; solid dark curve), Wagman et al (1982;dashed curve), and DeKock (1982;dotted curve). However, the %RH at 41°C reported by Yang et al (1994;dot) is too high.…”

Nature of Bound Water in Colloidal Systems

“…It also equaled the total energy change less the amount involved in entropy change. 4 Heat content: the total energy content, in calories, of a gram mole of a constituent. Actually only the change in Jleat content can be measured.…”

Europa's Crust and Ocean: Origin, Composition, and the Prospects for Life

“…The expected situation, wherever ice is present on Europa, is that there should exist a local water vapor pressure that would tend to cause salts to exist in their maximum hydration states. However, Carpenter and Jette (1923) and Keller et al (1986).
