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

• adhesion
• capillary action
• cohesion
• surface tension

Which is NOT a unique property of water?

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

Which statement best describes an effect of the low density of frozen water in a lake?

• When water freezes, it contracts, decreasing the water level in a lake.
• Water in a lake freezes from the bottom up, killing most aquatic organisms. 
• When water in a lake freezes, it floats, providing insulation for organisms below.
•  Water removes thermal energy from the land around a lake, causing the lake to freeze.
