Title: Effect of temperature on capillary pressure
Abstract: The effect of temperature on capillary pressure is one of several fascinating problems unearthed by J.R. Philip during his long career. In his classic paper written with Daniel de Vries, he assumed reasonably, but incorrectly, that the relative change in capillary pressure with temperature was equal to that of the surface tension of water. In fact the change for capillary pressure is roughly four times as large. Four mechanisms may be proposed to explain this discrepancy: expansion of water, expansion of entrapped air, solute effects on the surface tension of water, and temperature-sensitive contact angles. None of these explanations describes all of the pertinent data. A definitive explanation appears to be as elusive today as it has been at any time.
