This document discusses different states of matter and changes between states. It describes solids, liquids, and gases, and the processes of condensation, solidification, melting, and evaporation. It also defines pure substances as made of one component, while mixtures contain two or more components. Homogeneous mixtures have components that cannot be distinguished, while heterogeneous mixtures have visible components. Finally, it lists some common separation methods for mixtures like evaporation, filtration, decantation, and distillation.

1. Matter Changes

2. We Can Classify Matter
STATES OF MATTER
SOLID LIQUID GAS
Always occupies
the same space
and his volume
don’t change.
Change the shape
and his volumen
don’t change.
Change the shape
and his volumen.

3. Changes of State in Matter
1º
Condensatio
n: Is when a
gas changes
into a liquid.
2º
Solidification:
Is when a
liquid change
into a solid.
3º Melting:
Is when a
solid turns
into a liquid.
4º
Evaporatio
n: Is when
a liquid
turns into a
gas.

4. PURE
SUBSTANCES
AND MIXTURES
-Pure substances: is formed by only
one component.
-Mixtures: Are
formed by two
or more
components.
-Homogeneous
mixtures: The
components cannot be
distinguised.
-Heterogeneous
mixtures: The
components are
easily visible.

5. Separating Mixtures
Evaporation Filtration Decantation Distillation
They are
composed of a
liquid and a solid.
Evaporates the
water and leave
the solid.
Are composed of
liquid and a solid.
The mixture
passes through
paper but the
solid caught in the
paper.
Made of two
liquids of
different
densities. When
leave the
mixture the
denser liquid
put at the
bottom.
Separate of
two liquids.
The gas
obtained
return to the
liquid state.
