The contact between the solute and the solvent is improved.
Salt and sugar do not evaporate, but the water that they are dissolved in does.
Water with 1 gram of salt completely dissolved in it will freeze faster than an equal volume of water with 2g completely dissolved in it.
Evaporate the water, leaving the salt behind.
By heating it, by stirring it, and by Shaking it
If a saline solution (dissolved salt in water) is gently heated, the water will evaporate, leaving salt crystals behind.
I would think it would dissolve faster in fresh water, as the fresh water doesn't have anything dissolved in it yet whereas the salt water has dissolved salts and so less room for the sugar molecules. A. yes; sugar does dissolve faster than salt does, in fresh water.
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
No, salts are insoluble in kerosene oil.
A salt with fine granulation is dissolved faster; also the solubility increase with the temperature. Stirring improve the speed of dissolution. Any difference between iodized or not iodized salt.
Shaking is a Verb. Example: I am shaking the salt out of the salt shaker.
Yes, it is true; this is a method to obtain salt from sea water.
It does not matter what the material dissolved in water. The only thing that matters is how much is dissolved. So neither.
