The water condensation transition occurred between 80% and 85% RH in a and between 70% and 75% in b. The Kelvin equation relates the equilibrium vapor pressure of a fluid to the curvature of the fluid-vapor interface and predicts that vapor condensation will occur in pores or irregularities . The distance from the exit meniscus to the opening is expected to be short because, in our atomically flat capillaries, water moves much faster as liquid than vapour26. To account for this underestimation, the idea of a statistical film thickness, t, has often been invoked. ADS E 79, 067301 (2009). Plimpton, S.
