63 Science background for teachersMIXING AND DISSOLVING MATERIALSM ixing MATERIALS together forms a mixturewhere two or moresubstances are physically but not chemically combined and can beseparated again by physical methods such as sieving, filtering,evaporating etc. This means that the change can be reversed. A newmaterial is not formed as it is in a chemical reaction. Mixtures can bemade up of; solid in solid (muesli) gas in solid (pumice stone) solid in gas (smoke) gas in gas (air mostly made up of nitrogen and oxygen) liquid in gas (clouds, mist, aerosol) gas in liquid (oxygen in water) liquid in liquid (emulsion milk) insoluble solid in liquid (suspension muddy water) soluble solid in liquid (solution salt water).
