Particles Flashcards
Pure Substance
One type of Particle
Mixture
More than one type of particles
Homogenous
The particles are evenly spread, giving the mixture a combined look
Heterogenous
The particles are unevenly spread, giving the mixture a non combined look
Sediment
Forms a section at the bottom, due to the more dense solids sinking.
Solution
The particles mix to form a even look
Colloid
Particles that are slightly bigger, heterogenous, but do not form a sediment, usually cloudy.
Suspension
Large particles that form a sediment, heterogenous, opaque or cloudy. E.g pulp in juice.
Compound
A substance made of two or more elements chemically bonded to each other in a fixed ratio.
Molecule
A group of two or more atoms that are chemically bonded together.
Element
Periodic Table
Solute
The substance being mixed into the other substance
Solvent
The substance the solute it being mixed into.
Soluble
Able to be dissolved into another specific substance.
Insoluble
Not able to be dissolved into another specific substance.
Saturated
After being a soluble solvent, too much solute has been added, making it insoluble.
Concentrated
A large amount of solute compared to solvent.
Dilute
Less solute compared to solvent.
Supernatant
The layer above the sediment.
Filterate
The liquid or gas that passes through the filter.
Residue
The substance left above the filter that did not pass through.
Filteration
The process of filtering.
Sieve
A form of a filter.
Decantation
Forming a sediment, then carefully pouring out the supernatant.
Chromatography
A process that can be used to see the different pure substances in a solution.
Fractional Distillation
separates a liquid mixture into different substances using their boiling and condensation points
Steam Distillation
plant oils are mixed into water vapour to remove them from the plant, then separated back out when the water and oil have cooled
Volatility
how readily a liquid evaporates at a particular temperature
Crystilization
a separation technique that involves the evaporation of a solvent from a solution, leaving behind a crystallised solute
Distillation
separating a liquid through boiling, condensation, and collection
Distilate
the liquid collected during distillation
Transparent
See through
Translucent
Semi-see through
Magnetism
the force exerted by magnets when they attract or repel
Magnetic
the property of being attracted to magnets
Evaporation
evaporation the process where a substance changes from a liquid state to a gas
Transpiration
transpiration the process where plants lose water vapour from their surfaces
Irrigation
irrigation the supply of controlled amounts of water to grow crops
Greywater
greywater wastewater from non-toilet and non-kitchen plumbing
Blackwater
blackwater wastewater from toilet and dishwashing plumbing
