Question

Добавьте в воду мыльный раствор и пользуясь тем же капилляром что и в ходе работы измерьте высоту поднятия жидкости в нем результат объясните

Answer 1

В мыльном растворе высота поднятия примерно в два раза меньше, чем в воде. Это означает, что коэффициент поверхностного натяжения воды примерно в 2 раза больше, чем в мыльном растворе.

Answer 2

Experiment Explanation and Results

To measure the height to which the liquid rises in a capillary tube when a soap solution is added, you can follow these steps:

1. Prepare the Setup: Add the soap solution to the water and mix it well. 2. Use the Capillary Tube: Using the same capillary tube, measure the height to which the liquid rises.

The result of this experiment can be explained by the phenomenon of capillary action. When a soap solution is added to water and the capillary tube is used, the soap solution alters the surface tension and the adhesive forces between the liquid and the walls of the capillary tube. This change in surface tension and adhesive forces causes the liquid to rise to a different height compared to when only water is used.

The exact measurement of the height to which the liquid rises would depend on various factors such as the concentration of the soap solution, the diameter of the capillary tube, and the specific properties of the liquid being used.

Additional Information

If you need further details on the specific properties of soap solutions and their effects on capillary action, it would be beneficial to consult scientific literature or academic resources that delve into the physics and chemistry of liquids and surface tension.
