What word describes when water is attracted to other substances?

• cohesion

• adhesion

• capillary action

• surface tension

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
