Abstract
The invention relates to a liquid surface tension verification experiment tool, in particular to an automatic leveling device for liquid surface tension coefficient measurement and aims to solve the technical problems that the levelness of a metal part used in a liquid surface tension verification experiment at present is not easy to adjust. The automatic leveling device for liquid surface tension coefficient measurement comprises a leveling circular ring, an automatic level gauge and a bottom water tank, wherein the circumference of the upper end opening of the leveling circular ring extends outwards to form a boss; the automatic level gauge is suspended in the bottom water tank which is internally filled with a liquid and is suspended; the leveling circular ring penetrates through a first through hole from top to bottom and is limited at the lower end opening of the first through hole through limiting matching of the boss and a limiting platform. The liquid in the bottom water tank is adopted as a carrier for leveling adjustment, and very precise leveling can be theoretically achieved by using the automatic level gauge suspended in the liquid; in an experiment, the leveling circular ring can contact the surface of the liquid at a precise leveling posture, and the experiment precision can be ensured.
Description
technical field [0001] The invention relates to liquid surface tension verification experiment equipment, in particular to an automatic leveling device for measuring liquid surface tension coefficient. Background technique [0002] In college physics experiments, the measurement of liquid surface tension is a classic verification experiment, which is very popular among teachers and students. In order to allow students to learn the method of measuring surface tension and better understand the theoretical knowledge of liquid surface tension, most of the higher engineering colleges have set up this experimental course. Therefore, there are various methods and experimental instruments for measuring the surface tension coefficient of liquids, among which the leveling method and the pull-off method are more common. In the metal-liquid surface tension coefficient measurement experiment, no matter using metal sheets, metal wires or metal rings, there is a tricky experimental requir...
