Water Unique Properties

Capillary action is the result of adhesion. Which aspect of water is responsible for this?

• Nonpolar covalent bonds that enable water to dissolve other substances
  
• Polar covalent bonds that join molecules of water to other substances
• Hydrogen bonds between water and another substance
• Ionic bonds that enable electrons to flow through water and into another substance

Which of the following properties of water enables it to move from the roots to the leaves of plants?

• Water expands as it freezes.
• Water is an excellent solvent.
• Water exhibits cohesive behavior.
• Water moderates temperature.

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

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

Attractions between water molecules are called

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

The attraction that causes water and other liquids to form drops on thin films is called ________________. This is also water’s ability to be attraction to other water molecules.

• adhesion
• capillary action
• cohesion
• surface tension

Which is NOT a unique property of water?

• Frozen water floats on liquid water.
• Water covers most of the Earth’s surface and retains a large amount of heat.
• Water molecules stick to each other through hydrogen bonds.
• Water cools very rapidly.
