液体表面张力系数与温度和浓度的关系实验研究

Study on the Relationship between Liquid Surface Tension and Temperature and Concentration

实验采用拉平法,测出了不同温度和浓度下水和盐水的表面张力系数。通过对实验数据进行分析,得出了水和盐水的表面张力系数均随温度变化呈线性关系,盐水的表面张力系数随浓度的增大而增加。

The relationships between surface tension coefficient and temperature, concentration are verified in experiments, by which the surface tension coefficient of saline water in different temperatures and concentrations is obtained. Results show that the surface tension coefficient of water and saline is related to temperature and concentration.
