THE EFFECT OF FREEZING ON A CAPILLARY MENISCUS AND DISCUSSION

THE EFFECT OF FREEZING IS DESCRIBED ON A CAPILLARY MENISCUS AS OBSERVED IN EXPERIMENTS. EXPERIMENTS SHOW THAT UPON FREEZING THE CAPILLARY MENISCUS DISAPPEARS, AND THE WATER COMES IN DIRECT CONTACT WITH THE DOWNWARD-FREEZING ICE LENSES. DISTILLED WATER WAS FROZEN IN A VERTICAL CAPILLARY TUBE AND OBSERVED BY MEANS OF OPTICAL MAGNIFICATION. THE CHANGES WERE OBSERVED IN THE SHAPE OF A CAPILLARY MENISCUS UNDERGOING FREEZING CONDITIONS, AND THE CHANGES WERE FIXED PHOTOGRAPHICALLY. OBSERVATIONS SHOW: (1) WHAT HAPPENS TO THE MENISCUS IN THE REGION OF CONTACT BETWEEN THE WATER-VAPOR INTERFACE UPON FREEZING, (2) THE SOUNDNESS OF THE THEORETICAL ASSUMPTION WHICH FORMS THE BASIS FOR THE THEORETICAL-EXPERIMENTAL RESEARCH ON THE UPWARD MIGRATION OF SOIL MOISTURE UPON FREEZING, AND (3) THE RESULTS ESTABLISH THE FACT THAT UPON FREEZING THE UPWARD-TRANSPORTED SOIL MOISTURE IS IN DIRECT CONTACT WITH THE DOWNWARD-FREEZING ICE LENSES.
