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
