Theory
This theory states that all matter is made of tiny objects that are always moving and have spaces between them.
Particle Theory of Matter
This separation method is used to separate a solid from a liquid by passing the mixture through a porous material.
Filtration
This term describes a solution that contains a very small amount of solute relative to the amount of solvent.
Dilute
According to the Particle Theory, particles in this state of matter are locked in place and can only vibrate.
Solid
You have a mixture of iron filings and sand. Which tool is the most efficient for separating them?
A magnet
Often called a 'mechanical mixture,' this type of mixture has different parts that are clearly visible to the naked eye.
Heterogenous Mixture
This term refers to a substance made of only one kind of particle throughout.
Pure Substance
Most solid solutes, like sugar, become more soluble in water when this physical factor is increased.
Temperature
Which of the following is an example of a pure substance?
Distilled Water
If you wanted to separate a mixture of pebbles and fine silt from a dried-up Saskatchewan creek bed, which method would you use first?
Sifting (Sieving)
In a saltwater solution, the salt acts as this part of the mixture.
Solute
This process involves heating a solution to trap the solvent as a gas and then cooling it back into a liquid in a separate container.
Distillation
If you have 5g of salt in 100mL of water, '5g/100mL' represents this specific measurement.
Concentration
The Particle Theory states that there is always this between particles, even in a solid.
Empty Space
In the process of paper chromatography, substances are separated based on their ability to do what?
Dissolve and travel through a medium
Water is frequently given this title because it is capable of dissolving more substances than any other liquid.
Universal Solvent
According to particle theory, particles move faster when this is added to the system.
Heat (Thermal Energy)
This describes a solution that contains more solute than it should normally be able to hold at that temperature, often created by cooling a saturated solution slowly.
Supersaturated
When sugar dissolves in water, the sugar particles are attracted to the water particles more than to each other. This demonstrates which part of the Particle Theory?
Particles are attracted to each other
Which method would be best for recovering ONLY the salt from a salt-water solution if you don't care about keeping the water?
Evaporation
When a solution can no longer dissolve any more solute at a given temperature, it is described by this term.
Saturated
This term describes the mass of a solute that can be dissolved in a given amount of solvent at a specific temperature.
Solubility
When a substance like oil will not dissolve in water no matter how much you stir, the oil is said to be this.
Insoluble
A substance made of two or more different elements that are chemically combined (like CO2) is still a pure substance because it is a...
Compound
Sewage treatment plants use this method to allow heavy solid waste to sink to the bottom of large tanks so the clearer liquid can be removed from the top.
Settling (Sedimentation)
