What happens to water's density when it freezes?
Water resists quick changes in temperature and doesn't easily evaporate (or freeze); this is due to water's
Why is it important to use the term partial when describing charges on a water molecule?
How does the polarity of a water molecule play a role in its ability to form hydrogen bonds?
What property of water is responsible for the creation of surface tension?
When water freezes, it becomes less dense and floats on the surface of bodies of water. Explain why this is helpful to aquatic life.
