meniscus of water and mercury

to hog silicon's electrons. Copyright 2023 Quick-Advice.com | All rights reserved. I am telling you that." e.g. SCIENCE PHOTO LIBRARY. The meniscus is concave when adhesive forces are stronger than cohesive forces. Technology solutions to the ozone layer problem. the oxygen in the glass than the oxygen and the this concave meniscus is because the fluid is more attracted to the container than it is to itself. https://www.thoughtco.com/definition-of-meniscus-605883 (accessed May 1, 2023). So if water is held in containers made of different materials, it may have meniscus of different shapes depending on the electrnegativity of the material? you have two oxygen atoms. Angle of Contact Definition & Shape of Meniscus | AESL And so you can imagine all of a sudden, maybe this, let me see, And so you might imagine The IMFs of attraction between two different molecules are called adhesive forces. So why do, Posted 5 years ago. Science Photo Library's website uses cookies. When you have mercury liquid in a container, why is the meniscus upside down compared to all other liquids? Very interesting question and I had to an extensive google search too! Water has hydrogen bonding.what about mercury?does mercury repel glass tube?what is the force which makes mercury have more cohesive nature than adhesive nature? Mercury has a convex meniscus because the intermolecular forces between mercury atoms are stronger than those between mercury atoms and glass molecules of a tube. When liquid mercury is confined in a tube, its surface (meniscus) has a . Water meniscus is concave, mercury meniscus is convex. Helmenstine, Anne Marie, Ph.D. (2020, August 28). On the other hand, water forms a concave meniscus. Direct link to Ivana - Science trainee's post Actually it depends on th. the adhesive forces between the molecules of a liquid and those of the Convex menisci occur, for example, between mercury and glass in barometers[1] and thermometers. You might have even observed this before. And actually it would be very hard to find something that thin that's on the order of only a few molecules. has a partially negative "and has partially positive If I were to take a container of water. Consider what happens when water comes into contact with some surface. Video \(\PageIndex{1}\): An overview of intermolecular forces in action as surface tension, viscosity, and capillary action. the top of a convex meniscus or the bottom of a concave meniscus. The partially positive But it's actually not the case and I encourage you to try it. It is well known that water forms a concave meniscus while mercury
