Matter consists of small
particles that always move and collide among each other.
The kinetic theory of matter
stated the particles move freely when energy is absorb and move slowly when
energy is release, then they are cooled.
The kinetic molecular theory
used to explain the change physical state of matter.
Gas molecules are individual
particles that travel in a straight-line random motion. This will continue
until they collide or are acted upon by another force.
Gas molecules continuously
collide and transfer energy during these collisions. In an isolated sample of gas
the net energy is conserved.
The volume of the individual
gas molecules is negligible compared to the volume they occupy.
No forces of attraction are
considered to exist between the gas molecules.
