Structure & Properties of Water
Structure

1 molecule of water is made up of _________________________________
bonded with ___________________________.

The bond that forms water is a __________________________(between the
oxygen and hydrogen atoms).

Chemical formula: __________

________________________ of molecules of water make up
_________________________.
Polar Molecule

A molecule that has ____________________________ areas.

Also called a _______________________ or a polar ____________________.

___________________________ substances do NOT have _______________
ends.

The positive ______________________ends of 1 molecule are attracted to
the ________________________ of the ________________ of another
molecule.

The properties of: cohesion, adhesion, specific heat, universal solvent,
capillary action, and surface tension all happen because water is a
________________________________!
Capillary Action

The combines force of ______________________________________
____________________ and with the molecules of the ___________
_______________________.

_________________________ + __________________________
Surface Tension

The _______________________ across the surface of water that is caused by
the ______________________________ pulling on one another.

Makes the surface act like a _________________.
Universal Solvent

This is the ____________________ given to water.

Water dissolves LOTS of things.

Remember: SOLVENT: _____________________________________
SOLUTE: ________________________________________________

Other ______________ molecules can be dissolved by water.

Non-polar substances _________________ dissolve in water.

Why is water so good at dissolving things?

______________________________________.
Cohesion

Because water is a polar molecule, it is ________________________
_______________________.

Cohesion- the attractive force ________________________________

Water molecules like to _____________________________________.

Rubbing alcohol doesn’t like to _______________________________
As much as water.
Adhesion

Because water is a polar molecule, it is attracted to _______________
substances.

Adhesion- ________________________________________________
________________________________________________________.
Picture of adhesion:
Adhesion is going on
between the _____________
and the _________________.

Water molecules like to stick
stick to each other.
to other things.
Ex:
Ex:
Specific heat

Specific heat- the amount of energy _______________ to
___________________ the temperature of something ____________.

Water has a _________________________ specific heat.

That means it takes a lot of energy for water to ___________________
_________________________________.

This is because of the ______________________________ between water
molecules. It’s POLAR!
Density of ice vs. water

Ice is ________________ than liquid water.
