Properties of Water and Acid/Bases

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

Large bodies of water do not quickly fluctuate in temperature. Why?

• Water is a solvent.
• Water has a high heat capacity.
• Water acts as a buffer.
• Water is non-polar.

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

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.
