Matter and Mixtures
We use graduated cylinders to measure volume in this unit.
What is millilitres (mL)
The air we breath is a mixture. We can remove dust from the air using this.
What is a filter.
These are the three states of matter?
What are solid, liquid, and gas?
This type of solution has small amounts of solute in a solvent.
What is a dilute solution?
We used this process to separate black ink into its parts.
What is paper chromatography?
Of the two measurements, mass and weight, this one stays the same no matter where you are in the universe.
What is mass?
Crude oil can be separated into gasoline, kerosene, and diesel suing this process.
What is distillation?
All matter is made up of these.
What are tiny particles?
This type of solution has large amounts of solute in a solvent.
What is a concentrated solution?
A solution that contains more solute than it would normally be able to dissolve at a certain temperature is this.
What is supersaturated?
Matter is identified as being a mixture or this.
What is a pure substance?
Sawdust floats in water because of this property.
What is less dense than water?
All particles do this, regardless of whether they form a solid, liquid, or gas.
What is move and vibrate?
This is the measurement of the amount of solute dissolved in a certain amount of solvent.
What is concentration?
Hydrogen and Oxygen are both elements. Water (H2O) is this.
What is a compound?
What is a mechanical mixture or a heterogeneous mixture?
To separate a solution of salt and water, we would need to rely on this method.
What is evaporation?
This is why 50mL of water mixed with 50mL of sugar does not produce 100 mL of sugar water solution.
What is the space between particles causes the volume to be less than 100 mL.
A solution in which no more solute can be dissolved.
What is a saturated solution?
When we combine two substances, volume is not always conserved but this is.
What is mass?
Solutions are created by dissolving a solute in this.
What is a solvent?
Rock, gravel, and sand can all be sold for different amounts. The gravel company uses this to separate the different sizes.
What is a sifter or sieve?
These two processes help you dissolve sugar in water very quickly.
What is stirring and using hot water?
When we mix pepper and water, we see that pepper is this.
What is insoluble?
The physical property we used to separate staples from dirt.
What is magnetic attraction?
