Fig. 1. Differences in approximate apparent surface tension, ${gamma}$ , in N m 10^-3 for soils I–XII following adjustment to relative humidities (RH) of 32, 73, and 98% at 20°C compared with the apparent surface tension of the soils adjusted to 50% RH (median of three tests). No bar indicates no difference between RHs. Details concerning the apparent surface classes are given in Table 3.
