Essentially, in the alcohol solution, theres no surface tension (or, at least, not nearly enough to support a paper clip). This reduces the surface tension, and the water does not hold its round shape and thus spills. Number of drops . Science Physics Komal found that her vial of isopropyl alcohol showed a much better surface tension bubble shape (a higher bubble) than her vial of water. Yes, you can get drunk off rubbing alcohol. 47. Continue adding drops until the water spills. There are three factors that affect surface tension. Part 1: Surface tension and vortex When a liquid is swirled, a vortex is developed in which the surface level of the center of the liquid is substantially below the surface level of the perimeter. They are not as attracted to other alcohol molecules as water is to other water molecules. Only emails and answers are saved in our archive. The 70% concentration is universally used as a quite effective medical topical antiseptic and germicide. Where, v1 =surface tension of test liquid. Note: Even though there are many ways to compare the surface tension of water and alcohol, the procedure written below compares each liquid on the surface of a penny. The average diameter of Al2O3 particles were 100 nm. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material. Toll-Free:800-858-4043
