Turkey Test Review

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.

What property of water allows it to be such a versatile solvent that it is often called the "universal solvent?"

• Purity
• Polarity and cohesion
• High heat capacity
• Expansion upon freezing

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 ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
