Double Points!!!
It is a characteristic that can be observed or measured without changing the sample’s composition
Physical Propertie
It is the phase change in which matter goes from liquid to gas
Evaporation
In this type of mixture, the components have a uniform composition throughout the sample and cannot be seen at simple sight
Homogeneous Mixture
Is the technique of separating two or more dissolved solids which are present in a solution in a very small quantity
Chromatography

Extensive Properties
It is the phase change in which matter goes from gas to solid
Deposition
Is air a pure substance?
No
Why do different components on a mixture travel at different speeds when they are raised up by water on a paper chromatography?
Because of their different solubility levels
