2. States of Matter
The changes in matter
depend fundamentally on
the conditions of pressure
and temperature and are
determined by the
exchanges between
substances and the
environment around them.
4. It is characterized by structural rigidity and
resistance to changes of shape or volume.
Solid
5. Characteristics of solid state:
Not recover their own way.
A solid can be broken into fragments.
They cannot be scratched by other objects softer.
They have definite shape and volume is constant.
Its density is very high, that is why it is said that they
are “heavier”.

7. Liquid
Is the only state with a
definite volume but no
fixed shape.
The density of a liquid is
usually close to that of a
solid, and much higher
than in a gas.
8. Characteristics of liquid state:
Its cohesion strength is regular.
A liquid is able to flow and take the shape of a
container.
Some liquids resist compression, while others
can be compressed.
Is fluent.
This state of matter is actually the least
common in the known universe.

11. Characteristics of gas state:
The gas molecules are almost free.
Gases occupy the total volume of the container.
So definite shape.
Can be compressed easily.

14. Kinetic-Molecular Theory
In the solid state it has a
minimum of movement of the
particles.
In the liquid state the particles
vibrate in a certain spatial
region faster.
The gaseous state have the
higher kinetic energy.
