science Flashcards
Mixture
A substance made by combining 2 or more pure substances.
Solution
A type of mixture in which one substance dissolves in another, creating a see-through liquid. Example: Saltwater, sugar water, cordial.
Dissolve
To break up into tiny invisible particles.
Soluble
A soluble substance is a substance that can be dissolved. Example: salt and sugar are soluble in water, whereas sand is not.
Insoluble
A insoluble substance is unable to dissolve in a liquid. Example: sand and water.
Solute
The substance that is dissolved in a solution.
Solvent
The substance that preforms the dissolving in a solution.
Dilute
A solution with only a little solute in a lot of solvent.
Concentrated
A solution with a lot of solute.
Saturated
A solution in which the solvent cannot dissolve anymore solute. The additional solute will fall to the bottom.
Suspension
A mixture in which a substance cannot dissolve in the solvent, it will usually settle to the bottom of the container. Example: Sand + water, dust in air.
Magnetic separation
Used to separate magnetic substances from non-magnetic ones. Example: Iron filling from sand.
Gravity separation
Used to separate heavier substances from lighter ones. Example: Gold panning.
Sieving
Barrier with holes in it. Small substances can move through holes, larger ones can not. Example: spaghetti strainer.
Filtration
Similar to sieving, however uses filter paper with microscopic holes.
Centrifuging
Spinning machine that forces larger particles to the side then the bottom of the container. Example: Separating blood into plasma and red blood cells.
Chromatography
when a mixture is seperated by making it move through different substances
what is the difference between sewage and sewerage
sewage is the wastewater and sewerage is the pipes that take the wastewater away
