Only if the concentration is the same.
Yes. Rock salt, which is largely the same as table salt, will dissolve in water.
When salt dissolves in water, the amount of salt stays the same. The salt molecules spread out in the water but remain present in the solution. This is a physical change and does not involve the loss or gain of salt molecules.
Salt water is salty because of chemicals that are dissolved in the water. The water is still H2O, the same as fresh water.
the taste stays the same because when you drink the salt water it taste exactly the same
Same as the cold salt water.
no!
same, but salt water leaves the salt behind
No salt has a greater density.

The same
