Water: Structure and Properties

Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?

• Water is an acid.
• Water is a versatile solvent.
• Water has a high heat capacity.
•  Water acts as a buffer.

Water is often called the "universal solvent" because many substances can be dissolved in water. What property of water allows it to be such a versatile solvent? 

• purity
• polarity and cohesion
• high heat capacity
• expansion upon freezing

Water has a much higher specific heat than most other covalent compounds. What do you predict might happen if water had a low specific heat instead?

• Flooding would occur and animals would be forced to migrate
•  Harmful organisms living in water would reproduce at a rapid rate
• Organisms that are sensitive to changes in temperature would die
• Plants would not have enough water to effectively carry out photosynthesis
