Water wets glass because the force of adhesion between the glass molecules and water molecules is greater than the force of cohesion between the water molecules and glass molecules. Mercury does not wet glass because the force of cohesion is greater than the force of adhesion

Can mercury wet a substance?

Mercury is a metal unlike water which have hydrogen bonding. Mercury does not wet most substances, because of its high cohesion and low adhesion to the glass mercury will not wet glass. Cohesion, along with adhesion(attraction between unlike molecules), can help explain mercury phenomena. Mercury has a surface energy over 6 times greater than that of water so there is a much greater attractive force between the atoms of mercury than between the molecules of water, so mercury does not wet glass.


What liquid is not wet?

The "wetting" that happens when an object is immersed in a liquid depends on the surface energy of the object and the capilary forces in action on the surface of the liquid. for example mercury will not "wet" glass but water can wet the same glass.


List 3 basic liquids that do not wet a glass?

Mercury: Due to its high surface tension, mercury does not wet glass and forms droplets on its surface. Carbon tetrachloride: This liquid has low surface tension, which causes it to bead up on glass rather than spread out. Liquid bromine: Like mercury, liquid bromine does not wet glass due to its high surface tension property.


What are advantages of metal mercury?

It doesn't wet surfaces. It doesn't stick to glass.


What is strange about metal mercury?

Why is mercury not wet even though its liquid?

Mercury does not wet glass due to one of it's most significant properties. Mercury will not cling to the glass that contains it.


Why does a piece of glass float in mercury but sinks in water?

Glass floats in mercury because mercury is much denser than glass, creating a buoyant force that allows the glass to float. In contrast, water is less dense than glass, causing the glass to sink due to its higher density. The buoyant force in water is not enough to support the heavier glass object.


What are the advantages of mercury as a thermometeric liquid?

As mercury has a low specific heat yet is a good conductor of heat it has been the choice for thermometers. The ease of reading is due to the fact that the mercury does not wet the walls of the glass.

Why does alcohol cling to a glass rod while mercury does not?

Cohesion is the tendency of molecules to be attracted to similar molecules. Adhesion is the tendency of molecules to be attracted to dissimilar molecules.Water is both cohesive and adhesive, as is ethanol alcohol. The cohesiveness of water can be demonstrated by filling a cup with water and placing a wet clothe over the top of the cup, then flipping the cup upside down. The water will not entirely spill out of the cup.Mercury is cohesive, but not adhesive, so two drops of mercury will absorb one another, but dipping a clothe in mercury will not absorb it.The phenomenon of cohesion and adhesion can be understood by looking at the molecular structure and charge distribution of a molecule.
