No water can follow one of several paths that form the detailed cycle.
1. Put the mixture of gravel and salt in water. 2. Salt is water soluble, gravel not. 3. Filter: the salt is in the solution.
It's called the Water Cycle (Hydrologic Cycle).
Just a minute of evaporation of water, then salt is obtained!

It depends on amount of salt and water
It is a physical change because when salt is added to water,it is dissolved in it which only changes its physical appearance.

Yes, it does. When the water evaporates, it can not take the salt with it, so if you left a glass of salt water out, when it is evaporated the salt will be on the glass.
There are a few different ways you could calculate the concentration of a salt solution with known conductivity. You could compare this amount of salt with pure water for example and take notes on the differences.
put it in salt water
No evaporation will take place. Water cycle won't continue.
Salt dissolved in water has no appearance. Take a glass of water, sprinkle a little salt in it, stir. Salt disappears when dissolved.
It's called the Water Cycle (Hydrologic Cycle).
Desalination (to desalinate) means to take out the salt. If you boil salt water, the water turns to gas and leaves the salt behind.
