Seawater & Coastlines

What types of bonds give water special properties?

• polar

• nonpolar

• adjacent

• hydrogen

In what state of matter is water densest?

• gas

• liquid

• soli (ice)

Why is it a big deal that ice floats?

• it cools the ocean

• it insulates the water from the cold air

• it isn't

• it protects animals from ships

Water has a high heat capacity. What does this mean?

• It cools quickly

• it warms quickly, with little energy

• it takes a lot of energy to warm it up

• it freezes at low temperatures

Why is water's high heat capacity important?

• it keeps water temperature from changing too fast, harming sealife

• it can have a negative impact because water heats up too quick

• it keeps the polar bonds together

• it keeps salt water from becoming too fresh.

What two factors affect the density of water?

• polarity and conductivity

• polarity and salinity

• salinity and temperature

• temperature and radioactivity

Which is denser?

• saltwater

• freshwater

Which is denser?

• warm water

• cold water

Which will sink when mixed with the other?

• freshwater

• saltwater

Which will sink when mixed with the other?

• warm water

• cold water
