why does water always stick to containers? its near impossible to shake it off. no amtter how hard u pour, there is always water left in the container
-
With small amounts of water (droplets etc.) the force of surface tension is greater than gravitational pull or forces you manage to induce with shaking.
-
what is surface tension? in which direction does it act?
-
Also look into the chemical property of adhesion.
-
what kind of adhesion is it? i dont think water adheres to the container chemically, yet there also doesnt seem to be a physical force ???
-
it's a type of intermolecular bonding, between water molecules and the container surface
-
the capillary effect is based on water-surface interaction.
its is in part due to the polar nature of water
EDIT: spellcheck
-
There is no capillary action involved on large surfaces like a cup or container. It will be do to the macroscopic concept of adhesion described on the molecular level by Geodome.
-
is that kind of intermolecular bonding covalent? (making a guess... i dont really know much about these stuff)
