a fixed, uniform composition
- Mixtures
- Homogeneous
- you can't tell the difference
between substances
- Solution
- Can separate by:
Distillation - separates
materials based on boiling
points,
- don’t reflect light, doesn’t
form layers, can’t filter it
- Heterogeneous
- you can tell the difference
between substances
- Suspension
- Separate over time into
layers, (water and sand)
scatters light, if in water
- Can separate by:
Filtration - separates
materials based on
particle size
- A mix of substances to
form one substance
- Colloid
- Bigger particles than solution, smaller
than suspension, do not separate into
layers, reflects light (fog)
