layers, (water and sand)
scatters light, if in water
- you can tell the difference
between substances
- A mix of substances to
form one substance
- Colloid
- Bigger particles than solution, smaller
than suspension, do not separate into
layers, reflects light (fog)
- Bigger particles than solution, smaller
than suspension, do not separate into
