Surface Tension

Surface tension creates

A thin eleastic film on the surface of the water

When water sticks to something other than itself it's called

Adhesion

Capillary action is the result of

Adhesion and surface tension

Aperture

An opening

Adhesion of water to the walls of a vessel will cause

An upward force on the liquid at the edges and result in a meniscus

Negative atom

Anion

Positive and negative charges

Attract each other and try to pull together

Positive atom

Cation

Chlorine's chemical equation

Cl

Hydrogen

Covalently bonds

The interaction of particles at the surface of the liquid makes the surface behave as if it is an

Elastic membrane

Ionic bond

Electrons are transferred

Adhesion is the

Force of attraction between water and other materials

Surface Tension is defined as the

Force that acts on the surface of a liquid and tends to minimize the surface area

In water, there is a partial positive charge on the

Hydrogen atom

Cohesion

Is the force of attraction between water molecules

Sodium's chemical equation

Na

In water, there is a partial negative charge on the

Oxygen atom

Capillary Action

Property of water based on adhesion

Covalent bonding

Sharing of electrons: together in the valence

The film will

Support small objects so they will sit on the water without sinking

Wicking

The ability to draw moisture away from the skin-wicking fabric uses capillary action to keep moisture away from the skin

On the surface of water

The attractions are unbalanced

Under the surface of water

The attractions balance out

On the surface, the attractions are unbalanced because

The molecules have on the surface have one surface exposed to the air and no other water molecules to balance out the charges

Cohesion is caused by

The polarity between water molecules

Water will bead up because

The surface tension is pulling it into a spherical shape, which has less surface area than other shapes

Surface Tension is

The tightness across the surface of water that is caused by the polar molecules pulling on one another

When cohesion is more of a factor

The water forms spherical droplets

Without adhesion

There would be no capillary action

When adhesion is more of a factor

We get sheets of water

The lowest energy state occurs

When the maximum number of water molecules are surrounded on all sides by other water molecules

Adhesion

When water sticks to materials other than water

Capillary action is

waters' ability to move against gravity
