Abstract The air—water interfacial tension has been redetermined by the capillary rise and Wilhelmy plate methods at 25°C. The drop-volume method, using the Harkins—Brown corrections, gives good values for glass tips if appropriate precautions are taken. The effect of replacing air with He or N 2 at 1 atm. was not measurable, but CO 2 at 1 atm. gives a significant lowering of the interfacial tension. Measurements over the range 20–45°C are also reported.
