设计控温装置研究液体表面张力系数与温度的关系

Employing new temperature controlling device to investigate correlation between temperature and coefficient of liquids surface tension

介绍了自行设计、搭建的测量液体表面张力系数与温度关系的实验装置,用毛细管法测量了不同温度下水和乙醇的表面张力系数,得到了它们与温度的线性关系.利用此装置还可以进行其他对样品温度测控要求较高的实验.

A set of originally designed and installed device is introduced. By utilizing a capillary tube, the coefficients of surface tension of water and ethanol samples are measured under a series of temperatures; therefore, the linear correlation between temperature and surface tension of the liquid is demonstrated. Furthermore, this approach can be employed in other measurement which demands for the control of temperature.
