why the water is wet?
"Wet" is just a describing word that we use to describe something that has a liquid on or in it. So why does water act this way? Simply because it is a liquid and acts as such Water is a wetting liquid but Mercury is non wetting so not the all liquid are wetting it depends upon Adhesive and cohesive forces
the liquids having strong adhesive force than cohesive become absorbed on a solid surface and that surface becomes wet but the liquids having strong cohesive force can not absorbed on a solid surface so material remains dry and such liquids are non wetting liquids as Mercury, so water is wetting liquid due to its strong adhesive force.
So why liquid has more adhesive force than cohesive??
Molecules liquid state experience strong intermolecular attractive forces. When those forces are between like molecules, they are referred to as cohesive forces. When the attractive forces are between unlike molecules, they are said to be adhesive forces.
The adhesive forces between water molecules and the walls of a glass tube are stronger than the cohesive forces lead to an upward turning meniscus at the walls of the vessel and contribute to capillary action. The attractive forces between molecules in a liquid can be viewed as residual electrostatic forces and are sometimes called van der Waals forces or van der Waals bonds.
thanks for your reply prakhurluv..
ur welcome.......
Water is wet because water is a fluid. Anything that is fluid in substance is considered wet. The term wet can also be considered a descriptor term. Therefore, water is wet.
thanx for your ans dean.shyy
