This document discusses the properties and states of matter. It defines properties as things that can be measured, and identifies shape, mass and volume as key physical properties used to determine the state of a substance. Matter can exist in three main states - solid, liquid and gas - depending on how tightly or loosely packed the particles are and how much they move. The kinetic molecular theory provides an explanation at the microscopic level, describing particles in different states as moving at different speeds and with different degrees of attraction between them. Temperature affects the kinetic energy and motion of particles.

4. Properties of Matter
Properties Is something that we can
measure.
The physical properties we need to look
to determine the state of matter is
shape mass and volume.
Mass is the amount of matter in an
object.
Volume how much space an object can
occupy.

11. Physically matter exist in 3 phase
1. Solid
2. Liquid
3. Gas
4. Plasma –additional
Molecules –combination of 2 or more atoms
Atoms-from Greek word mean indivisible , a
greek philosopher who 1st discover it name
Democritus.

12. Macroscopic are properties that
can be observed by the 5 human
senses.
Microscopic are too small to be
seen even with the aid of the very
best of microscopes.
Solid ,liquid and gas can be
distinguished from each other on a
microscopic level based on their
shape and volume.

13. Solid particles are moving very slowly and
packed tightly together in a fixed position.
Liquid particles are closed together but
they can slide past one another
,consequently they move faster than solid
particles.
Gas particles on the other hand are
moving very rapidly and they experience
very little attraction for each other.in fact,
they fly off in every direction.

14. Matter regardless of its state it is
always in constant ,random motion
and hence possesses energy of motion
known as kinetic energy that is
dependent on the temperature.
This means that as you increase the
temperature, the atoms and
molecules will gain more energy as a
result, they will move even faster.

15. Kinetic molecular theory of matter
1. All matter ,be it in solid ,liquid or gas state are
made of tiny particles known as atoms.
2. Particles are in constant ,random motion.
3. Particle and motion make kinetic energy and
their motion increase as they gain energy.
4. There is a transfer of energy between
particles(atoms and molecules) as these
particles collide with each other.
5. Molecular motion is greatest in gases ,less in
liquids, and least in solid.

16. Kinetic molecular theory is very useful
in explaining why the states of matter
differ in movements and
arrangements .also, it describes the
forces between molecules and the
energy that they possess , as well as
the effect of temperature and
pressure on matter.
