ANOMALOUS GAS-LIQUID INCLUSION MOVEMENT.

Abstract

Gas and liquid inclusions in almost all solids move toward the heat source when a temperature gradient is applied. However, when an inclusion in these same solids contains both liquid and gas it instead may move away from the heat source. This phenomenon has been observed in NaCl, ADP, AgNO3, and a 12% camphor-anthracene mixture. The hypothesized mechanism invokes evaporation and condensation combined with circulation engendered by the dependence of surface tension on composition. (Author)
