Properties of Water Quiz

What property of water allows it to behave differently than other liquids?

• Density

• Polarity

• Viscosity

• Opacity

Which of the following is NOT a characteristic of water?

• Expands as a solid

• Has a high specific heat

• Has a basic pH

• Has a neutral pH

What causes water molecules to be polar?

• Differences in electronegativity between the O and H atoms

• Similar electronegativities between the O and H atoms

• Equal sharing of electrons between the O and H atoms

• Lack of hydrogen bonds between water molecules

Why do hydrogen atoms in a water molecule have a slightly positive charge?

• They gain electrons from the oxygen atom

• They lose electrons to the oxygen atom

• They share electrons equally with the oxygen atom

• They do not interact with the oxygen atom

What type of charge does the oxygen atom in a water molecule carry?

• Slightly positive

• Highly positive

• Slightly negative

• Highly negative

How are atoms in different water molecules attracted to each other?

• Positive hydrogen atoms attract negative oxygen atoms

• Negative hydrogen atoms attract positive oxygen atoms

• Positive oxygen atoms attract negative hydrogen atoms

• Negative oxygen atoms attract positive oxygen atoms

What is cohesion as described in the context of water molecules?

• The repulsion between water molecules and other substances.

• The attraction of water molecules to other water molecules.

• The attraction of water molecules to oil.

• The process by which water molecules freeze.

Which example illustrates adhesion?

• Water freezing into ice

• Tree frog clinging to glass

• Water forming droplets on a waxed surface

• Oil spreading on the surface of water

What is a common effect of cohesion among water molecules?

• Evaporation

• Surface tension

• Boiling

• Condensation

What process in the hydrologic cycle involves water moving from plants into the atmosphere?

• Condensation

• Evaporation

• Transpiration

• Runoff
