Which of the following properties of water enables water molecules to stick to one another?

• Water expands as it freezes.

• Water is an excellent solvent.

• Water exhibits cohesive behavior.

• Water exhibits adhesive behavior.

As the sun shines on bodies of water, they can absorb great amounts of its energy without a large fluctuation in temperature. Which special property of water allows for this?

• Water exhibits cohesive behavior

• Water is a versatile solvent.

• Water has a high heat capacity.

• Water has a pH of 7

When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

If this is a floating ice sheet, which property of water is this polar bear relying on? 

• Surface Tension

• Cohesion

• Adhesion

• Density

Capillary Action is key for

• Water moving from roots to leaves in plants

• Air moving from mouth to lungs

• Ice floating on water

In the picture above, ice cubes are shown floating on top of a glass of water. Which of the following hypotheses does this observation prove true?

• Liquid water has a high heat capacity

• Liquid water exhibits strong cohesive properties

• Liquid water is more dense than frozen ice cubes

• Liquid water is less dense than frozen ice cubes

Select all of the following choices that fall under the category:

properties of water

• Water expands as it freezes

• Water contracts as it freezes

• Water can dissolve any substance, including oil

• Water is extremely cohesive and adhesive

• Water has a high heat capacity

Why can water have no net charge but have slight charges in different parts of the molecule?

• The oxygen end is slightly negative and the hydrogen end is slightly positive

• The hydrogen end is slightly negative and the oxygen end is slightly positive

• The hydrogen and oxygen ends change in polarity

• Because it is hydrophobic
