Abstract

The surface tension of liquid iodine was measured by differential capillary rise method at various temperatures above the melting point. A paraffin bath with mercury regulator was used to maintain constant temperature. The height of the meniscus of liquid iodine in the capillary tube was measured by a travelling microscope. The measured values of surface tensions at $125.0^{\circ},135.0^{\circ}, 145.0^{\circ}$ and $155.0^{\circ}$ were 36.88, 35.87, 34.83 and 34.04 dyne/cm, respectively. Calculated Eotvos constant from the surface tension, data. experimentally obtained, were consistent through the temperature range.

액체 요오드의 표면장력을 측정하기 위하여 새로운 장치를 고안하고 differential capillary rise method를 써서 $125.0^{\circ}C,\;135.0^{\circ}C,\;145.0{\circ}C$ 및 $155.0^{\circ}C$ 에서 각각 36.88, 35.87, 34.83 및 34.04 dye/cm의 값들을 얻었다. 이 측정된 값들로부터 Eotvos 상수를 구해본 결과 각 온도에서 비슷한 값을 보여주고 있음을 알았다.
