Solution: a special mixture formed when a material(s) dissolving in a liquid: it is transparent. It has two part: the solute/solid part and the solvent/liquid part can be separated by evaporation.
Dissolving:a process in which one material (solid) spreads out evenly into another material (liquid) , so that the first material seems to dissappear.

Evaporation: cause liquids to dry up; the liquid turns into gas and disperese ( spreads out evenly) into air, leaving any dissolved
Solute: the soild part of a solution.
Solvent:the liquid part of a solution.
Saturated solution: when a solute (soild) dissolves in a solvent (liquid) until no more will dissolve (no excess solid left over).

Concentrated: an amount of material (solute/solid) dissolvedin a certain amount of liquid; the higher amount of solute the higher level of concentration.
Dilute:to make a solution less concentraded usually by adding more liquid/solvent.
Fact: when a solution evaporates, the dissolved solid material is left behind (usually in crystal form).
Fact: salt (or any solute) will dissolve in water (solvent) until it reaches saturation. No more salt will dissolve once saturation reached.
Fact: as the amount of solute ( solid) in a solution increase the concentraion
Fact: when an equal amount (volumes) of two solutions- for example each solution is 100ml - are copareed on a balence
Dilute: to make a solution less concentrated usually by adding more liquid/solvent.
Chemical reaction:when two or more materials/chemicals) are mixed together and a change occurs ( a new materials is formed- gas, solid or liquid).
