Which property of water means that each of its molecules has a positive and a negative charge on opposite sides?

• reslesion

• surface tension

• adhesion

• cohesion

Where are the positive and negative charges located on a water molecule? (which one is on the hydrogen atom and which one is on the oxygen atom?)

• located ontop of each other so that the charges even out and are negated

• located next to each other even though charges are opposites

• 1. located on opposite sides and hydrogen is positive and oxygen is negative

• located on adjacent sides

What are the bonds called that form between water molecules due to these charges?

• capilary bonds

• water bonds

• hydrogen bonds

• capillary action

Which property of water allows ice to float on the surface of liquid water?

• surface tension

• capillary action

• adhesion

• cohesion

What is the relationship between monomers and polymers?
