Which statement explains why water molecules stick together?

• both sides are negative

• one side has a positive charge and the other side has a negative charge

The ability of water molecules to stick to each other, creating surface tension is called:

• Cohesion

• Adhesion

• Insulation

• Ph

The pH scale is a range from:

• 1-7

• 0-14

• 1-14

• 1-20

When salt is dissolved in water, water is the 

• reactant

• solute

• solvent

• solution

Which end of the water molecule has a slightly positive charge?

• the oxygen end

• the hydrogen end

• both ends are slightly positive

• neither end is positive

What word describes when water is attracted to other substances?

• cohesion

• adhesion

• capillary action

• surface tension

Capillary action allows water to get from the roots to the top of trees. This is a result of

• high specific heat of water

• cohesion and adhesion

• ice floating

• potatoes

Why does ice float?

• As water freezes, it expands and its density decreases.

• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.

• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.

• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
