Any material that occupies space and has mass
The characteristics that are used to describe matter. Every material has its own set of properties
A mixture contains more than one kind of matter combined in such a way that each keeps its own properties
Mixtures that are made up of parts that can be seen. Made up of parts or mixed
Materials that have only one set of properties. Every part of the material is the same
A substance made of more then one kind of material, where the different materials can be easily identified
A mixture in which very small particles of one substance are distributed evenly throughout another substance. The particles are generally larger than those in a solution, and smaller than those in a suspension. Paints, milk, and fog are colloids.
Another name for a homogeneous mixture.
A material made up of only one kind of extremely small particle.
Particle Theory of Matter
the theory that scientists use to explain the properties of various mixtures and substances
Forming a solution by mixing two or more materials
The substance that dissolves in a solvent to form a solution.
The substance that dissolves the solute in a solution
To be able to be dissolved in a particular solvent
To not be able to be dissolved in a particular solvent.
A solution that contains more solute than would normally dissolve at a particular temperature
A process of separating the parts of a liquid solution. The solvent is heated to change it into a gas, then condensed back into a liquid.
A process of removing the salt from salt water.
Water that contains a high proportion of dissolved minerals
Water that contains few dissolved minerals
Undissolved material that settles over time to the bottom of a container.
A solution that contains relatively little solute for the amount of solvent
A solution that contains a lot of solute for the amount of solvent
A solution in which no more solute will dissolve at a particular temperature
A solution that more solute could dissolve in at a particular temperature
A measure of how much solute can dissolve in a given solvent at a given temperature.
A solution containing more solute than would normally dissolve at a particular temperature.
The temperature at which air becomes saturated with water vapour, causing precipitation
Rate of Dissolving
The measure of how fast a solute dissolves in a solvent
The bends, also known as decompression sickness (DCS) or Caisson disease occurs in scuba divers or high altitude or aerospace events when dissolved gases (mainly nitrogen) come out of solution in bubbles and can affect just about any body area including joints, heart, lungs, skin, and brain.
The source of most fuels used today-gasoline, diesel fuel, and kerosene, for example.
The process that yields all of the different petroleum products
The process of changing a liquid to a gas
To convert into a gaseous state
These are new products made from petroleum. There are over 500 000 different petrochemicals.
A mineral or group of substances that contain valuable substances. Iron ore or gold ore, for example.
Matter that has a uniform and definite composition
The process of using a strip of absorbent paper to separate the different substances in a mixture.
A heterogeneous mixture of one or more solid substances in a liquid. The particles of the solid substance spread, or become suspended, but do not dissolve. Eventually, the solid particles will settle to the bottom of the liquid.
The process of passing a mechanical mixture through a sieve to separate the larger pieces of matter.
The settling of substances at the bottom of a liquid.
The process of using a filter paper to separate large particles from a mixture as the liquid is poured through it. The cleaner water that remains at the bottom is called filtrate, and what is left on the paper is called residue.
A homogeneous mixture or solid solution of two or more metals.
