|
Carbon dioxide
|
This gas makes upless than 1% of air, has the shorthand of CO2 and is made in the labusing acid and carbonate – vinegar and baking soda.
|
|
|
Concentrated |
refers to a solutionthat contains a large number of solute particles dissolved in a small amount ofsolvent.
|
|
|
Condensation
|
refers to a change of state from a gas to a liquid as the particles in the gas lose energy. Eg. water vapour condensing on the bathroom mirror.
|
|
|
Dilute
|
refers to a solutionthat contains a small number of solute particles dissolved in a large amount ofsolvent. |
|
|
Dissolving |
Dissolving happenswhen one substance disappears into a liquid to form a solution. Eg. Salt dissolves in water |
|
|
Distillation
|
The process ofseparating a liquid from a mixture by boiling it and condensing the vapour thatevaporates off. Eg. Separating water from sea water
|
|
|
Evaporation
|
refers to a change ofstate from a liquid to a gas as the particles in the liquid gain energy. Eg. water boils and turns to steam
|
|
|
Filtration
|
The process of separating a mixture by passing a liquid through a filter in order to remove the insoluble particles. Eg. Separating sand from water
|
|
|
Filtrate
|
Filtrate is the liquid that has passed through the filter after the filtration process. What remains in the filter is normally the residue. Eg. Water is the filtrate when we filter sandy water.
|
|
|
Immiscible
|
describes two liquidsthat are not soluble in each other and form distinct layers. Eg. Oil and water are immiscible liquids mso-s����b2
|
|
|
Insoluble
|
A substance is notable to be dissolved in a solvent. Eg.Sand is insoluble in water.
|
|
|
Mixture |
A mixture is made upof different substances that are not chemically joined together so they can beeasily separated. Eg. Salt and water |
|
|
Matter |
Matter is anything that has mass and occupies space. Eg. Water is matter. Most matter exists in three states; solid, liquid and gas. |
|
|
Oxygen |
This gas makes uparound 21% of air, has the shorthand of O2 and is made in the labusing hydrogen peroxide andmanganese dioxide |
|
|
Solidification |
refers to a change ofstate from a liquid to a solid as the particles in the liquid lose energy. Eg. Melted wax solidifies on the candle. |
|
|
Solubility |
Is a measure of how much solutewill dissolve in a volume of solventSolubility usually increases with temperature |
|
|
Solute |
Is the substance thatdissolves in the liquid (the solvent) to form a solution. Eg. Sugar is solute we often use. |
|
|
Solvent |
Is the liquid inwhich a solute dissolves to form a solution. Eg. Water is the main solvent we use |
|
|
Sublimation |
refers to a change ofstate from a solid to a gas, with no liquid phase, as the particles in thesolid gain energy. Eg. Iodine and dry ice. |
