Pure vs Impure
This type of substance contains only one kind of particle, like distilled water.
What is a pure substance?
The substance that does the dissolving in a solution
What is a solvent?
This method removes a liquid from a solution to recover the solid that was dissolved in it.
What is Evaporation/Crystallization?
When butter softens on a warm pan without burning.
What is melting?
This is the temperature at which a liquid turns into gas.
What is Boiling Point?
A mixture in which solid particles are suspended in a liquid but will eventually settle out is called this.
What is a suspension?
A solution like saltwater, where the solute is evenly distributed and the mixture looks the same throughout.
What is a homogeneous mixture?
This apparatus is used to separate two immiscible liquids that have different densities.
What is a separating funnel?
Particles gain enough energy to break free from the surface of a liquid.
What is evaporation?
The ability of a substance to dissolve in another substance.
What is Solubility?
Milk looks uniform when poured, but it is actually a mixture in which tiny particles are dispersed throughout a liquid.
What is a colloid?
This weak acid is diluted in water as the solute in vinegar.
What is acetic acid?
A mixture of iron filings and sulfur can be separated using this technique.
What is magnetic separation (magnetism)?
When a cold soda bottle is left out on a warm day, tiny water droplets appear on the outside.
What is condensation?
This term describes a solid’s ability to be hammered or rolled into sheets.
What is Malleability?
This type of substance cannot be broken down into anything simpler by chemical means.
What is an element?
The maximum amount of solute a solvent can dissolve at a given temperature
What is a solubility limit (Limit of Solubility)?
A mixture is heated so that one substance evaporates. The vapour is collected and condenses into a liquid.
What is simple distillation?
Dry ice placed in a drink produces smoky clouds that disappear into the air.
What is Sublimation?
This property determines why copper can be stretched into wires but sulfur cannot.
What is Ductility
Steel is widely used in construction and tools because it is strong and durable. It is primarily made of iron combined with this element.
What is Carbon?
A solution that contains more solute than it can normally hold at room temperature. Made by heating then cooling carefully.
What is a supersaturated solution?
This method separates two miscible liquids with very similar boiling points by repeated vaporization and condensation.
What is fractional distillation?
This process occurs when frost forms on a surfaces in winter, changing water vapor directly into solid ice.
What is deposition?
An increase in this causes particles to move faster, which can lead solids to expand, liquids to evaporate, and gases to exert more pressure.
What is Kinetic Energy?
