Terms and Definitions
The substance that dissolves in a solution.
What is the solute?
How would you separate a bunch of different coloured gumballs?
What is sorting?
A mixture where you can easily see/feel the difference between the parts.
What is a mechanical mixture/heterogeneous mixture?
The state of matter where the particles are packed tightly together.
What is a solid?
The state of matter where the particles are packed the most loosely.
What is gas?
The substance that does the dissolving in a solution.
What is the solvent?
How would you separate a bunch of pieces of metal from a pile of sand?
What are magnets?
A mixture in which solute particles dissolve into solvent particles.
What is a solution?
Name one of the points of particle theory.
What is: particles are always moving, everything is made of particles, particles speed up when they are heated, particles are attracted to each other, particles in a pure substance are all the same.
Name one tool used to clean up an oil spill.
What are: booms, boats, sieves, sponges, wood chips, surfactants, hair, etc.
The term that describes a solute that won't dissolve.
What is insoluble?
How would you separate water from minerals/dirt to make it drinkable?
What is filtering?
A mixture where the solid particles will eventually sink to the bottom of the liquid.
What is a suspension?
Why can you pour a liquid and not a solid?
What is the particles are loosely packed and able to move in a liquid and not in a solid?
If a solute is able to dissolve in a solvent then it is called....
The term that describes a solution that could still dissolve more solute.
What is unsaturated?
How would you separate a mixture of sugar and water?
What is evaporation?
A mixture such as oil and water where the particles do not mix and form small bubbles.
What is an emulsion?
Which state or states of matter do not have a fixed shape?
What are liquid and gas?
Mayonnaise is an example of what kind of mixture?
What is a colloid?
The term that describes the ratio of the mass of solute to the volume of solvent. Measured in g/mL
What is concentration?
This process is used to separate different liquids such as ethanol and water and requires a special Apparatus.
What is distillation?
A mixture that looks like a solution where the particles do not dissolve but instead stay floating or "suspended."
What is a colloid?
Which state or states of matter do not have a fixed volume?
What is gas?
