Some adult insects are unable to swim but are able to walk on the top of water.  What characteristic of water enables these insects to walk on the top of water?

• heat capacity
• solvent properties
• solute properties
• surface tension

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

• covalent bonds result in water cohesion
• hydrogen bonds result in water cohesion (surface tension)
• water striders have adapted to take advantage of water cohesion
• low surface tension of water

Attractions between water molecules are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds
