The interrelationship between the temperature and surface tension of a liquid is an inverse relationship. As the temperature of a liquid increases, its surface tension decreases, and vice versa. This is because surface tension is a result of the cohesive forces between the molecules in a liquid. As the temperature increases, the kinetic energy of the molecules also increases, causing them to move more rapidly and become less attracted to each other. This results in a decrease in the cohesive forces and, consequently, a decrease in surface tension.The capillary rise method is a common technique used to measure the surface tension of a liquid. The method involves the following steps:1. Choose a clean, narrow glass tube capillary tube with a small diameter. The diameter should be small enough to allow the liquid to rise in the tube due to surface tension.2. Immerse the capillary tube vertically into the liquid whose surface tension is to be measured. Ensure that the tube is clean and free of any contaminants that could affect the results.3. Observe the liquid as it rises in the capillary tube due to the surface tension. The liquid will rise until the weight of the liquid column is balanced by the surface tension force acting around the circumference of the tube.4. Measure the height h of the liquid column in the capillary tube above the liquid's surface level in the container.5. Measure the radius r of the capillary tube using a microscope or other suitable method.6. Determine the density of the liquid, either by measuring it directly or by referring to a standard reference.7. Measure the acceleration due to gravity g at the location where the experiment is being conducted.8. Calculate the surface tension of the liquid using the Jurin's Law formula: = * g * h * r / 2 where is the surface tension, is the density of the liquid, g is the acceleration due to gravity, h is the height of the liquid column, and r is the radius of the capillary tube.By following these steps, the surface tension of a liquid can be determined using the capillary rise method. It is important to note that this method is most accurate for liquids with relatively low surface tension and may not be suitable for liquids with very high surface tension. Additionally, the method assumes that the liquid wets the capillary tube completely, and the contact angle between the liquid and the tube is zero.
