Dissolving: - Is a physical process where the substance retains its own physical Characteristics but just changes state or shape. The solubility of a solute is the mass of the solute that dissolves in 100g of solvent at a certain temperature; the solute can be solid, liquid or gas that dissolves in the solvent. Water is the most common but there are many others including ethanol (alcohol) and trichloroethene. I also found out from research that if you dissolve salt in water, both the freezing and boiling point of water are affected. The normal boiling point of water is 100 degrees and it increases if salt is added. The addition of salt also lowers the freezing point of water. When salt is put in water, the sodium and chloride atoms are pulled apart by the water....
