Answer 2

A. Saltwater is denser than freshwater. You can actually stack layers of colored water that have different salt conc. if you are really careful. I've done it a few times for students. It is really cool.

Answer 7

Answer 8

@mathlover2014 Yes, temp is important, but not nearly as important as salt in relation to water density.

Answer 9

oh cool

Answer 10

In fact, water will sink as it cools until a certain point. If I recall correctly this is around 39 F. As the temp gets lower than that water actually begins to expand and becomes less dense. This is why ice floats, which we should all be thankful for. If ice didn't float than all water on earth would likely freeze solid and life would have probably never evolved past small single celled things.
