Water Vocab

Cohesion

Cohesion

When water sticks to itself

Adhesion

When water sticks to other objects

Polarity

-Polar or non-polar

-water polarity allows it to dissolve other polar substances easily

-when a polar substance is put in water, the positive ends are attracted to the negative ends of the molecule and vise versa

Universal Solvent.

Water is the universal solvent because it dissolves most substances.

Solubility

The degree in which a substance dissolves in a solvent to make a solution

Capillary action

The movement of water within the spaces of a porous material due to the forces of cohesion, adhesion, and surface tension

(Remember flowers in class)

Surface tension

-The property of a surface that allows it to resist an external force due to the cohesive nature of water molecules

-a force which causes a layer to behave like an elastic sheet or skin

-molecules at the surface form a stronger bond

Meniscus

A curve in the surface of a molecular substance (water) when it touches another material.
