Because salt consumes intermolecular space
It makes the water more dense.
Because it is more dense
salt makes the water denser, so things that are now less dense than the salt water will float
salt water is more dense than tap water
Salt water will be more dense than the water, but less dense than the salt.
Cold water is more dense.
Water is pure by nature, however it gets dense due to different impurities. Impurities such as salt and tiny minerals cause the water to get dense.
Salt would make water more dense when dissolved in it.
Water in general is not more dense in Utah. The water of the Great Salt Lake, however, is very ... um ... salty. The dissolved minerals in it make it more dense. The Great Salt Lake is actually significantly saltier than ocean water.
Salt
Water becomes dense when it is more saturated than absorbing a solution. For example, salt with make water more dense because as more salt is added, it becomes saturated.
Because of the salt - salt is denser than water.
