Stupid ME - Meniscus

"G&G" asked...............

Meniscus, in effect does not float.

(1) It is the curved surface tension of the liquid in any container, or (2) The shape assumed by the surface of a liquid in a cylindrical container, or (3) Meniscus is the concave curve of a liquid surface in a graduate or narrow tube. Caused by surface tension.

Google is your friend!!!!!

Just to elaborate:

The meniscus forms in any liquid because the edges, which come in contact with the container, experience some friction which resists the pull of gravity and holds them higher than the liquid not in contact with the container. The curved surface is held together by surface tension, giving the familiar shape. Think of a piece of string that you hold loosely between your two hands: it will sag in the middle relative to the ends that you hold. That's exactly what's going on with the molecules in the liquid.

Hi Mark Would you elaborate on that and explain mercury's behaviour? It's a liquid too, isn't it? Thx in advance Anders
