1. Define the term salinity
The amount of salt in something
2. If you add salt to a water solution, will a hydrometer float higher or lower in the water?
lower because it was more dense
3. What effect does the addition of salt have on the properties of water?
it makes the salinity level's higher
4. Is it easier to float in the ocean than a swimming pool?
a pool because an ocean has more salt than in a pool
5. Define the term density
a ratio of the amount mass per unit volume
6. The salinity of seawater is also affected by the temperature of a body of water. Explain how temperature causes differences in the salinity of water
because when it's hot, the molecules of the salt start to move more and multiply
