Which part(s) of a water molecule has/have a partial negative charge?

the one oxygen (O) atom

What is the tendency of a fluid to resist flow?

viscosity

A water strider can skate along the top of a pond because:

hydrogen bonds result in water cohesion (surface tension)

A molecule with electrically charged areas is called a _______________.

polar molecule

polar molecule

Which property of water will cause water to bead up on glass?

Adhesion

Why does ice float?

As water freezes, it expands and its density decreases.

The attraction that causes water and other liquids to form drops on thin films is called ________________. This is also water's ability to be attraction to other water molecules.

Cohesion

Water droplets take a spherical shape because of ____________

Cohesion

tendency of molecules of the same kind to stick to one another

Cohesion

Water is a universal solvent because it...

Dissolves most substances

Attractions between water molecules are called

Hydrogen Bonds

What two elements make up water?

Hydrogen and oxygen

What property of water helps to moderate earth's temperature

Specific heat capacity

Water is polar because...

A leaf gently floats on a pond. Which of the following statements best explains why the leaf stays on top of the water?

The water molecules are held together by hydrogen bonding.

Which is NOT a unique property of water?

Water cools very rapidly.

Which statement best describes an effect of the low density of frozen water in a lake?

When water in a lake freezes, it floats, providing insulation for organisms below.

What word describes when water is attracted to other substances?

adhesion
