A water strider can skate along the top of a pond because:

• specific heat
• surface tension
• adhesion
• capillary action     

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

Why is water considered a polar 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 are covalently bonded     
• Because it is hydrophobic

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Capillary action pulls the water molecules up 
• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves
