Solution :
PLASMA..
The matter which composed the Universe was so hot that
everything
was in the form of plasma.
Thus, in the very beginning, plasma was thefirst state of
matter.
Form of Matter (
Phase )
Generally speaking we associate the four states of matter with
different
domains of temperature. As the temperature increases the
substance
passes from solid to liquid, through gas, to a plasma. The solid,
the
liquid and the gas are composed of a very large number of
molecules
(or atoms). In these phases of matter the heat is an expression of
the
molecular motion. In these three phases the molecules or atoms
are
moving as one unit.
Structure of Plasma.
A plasma is composed of a very large
number of
free electrons and ions and in this phase of matter the heat is the
expres-
sion of the separate electron and ion motions.a gas is normally an
electrical insulator, that is, electric currents cannot
easily pass through it. However, by heating the gas to
appropriate
temperatures, we found that the insulator gas becomes a good
electrical conductor. The gas is transformed into a plasma which
consists
of free electrons: the carriers of the electric currents.
How hot pocket become a gas or plasma,
Now, if we increasing temperature that means we puting more
energy in system so,All material can be brought to a gaseous state
by inserting the appropriate amount of energy. In a gas, the
molecules or the atoms move
freely inside the vessel, colliding mainly with the walls of the
vessel. If
the gas is not inside a vessel it diffuses into the air and
eventually spreads
throughout the atmosphere. If the energy is further increased,
the
molecules break up into their atomic constituents. What happens if
we
further increase the energy in our system? Because the atom has
an
internal structure, it will break into pieces just like the
molecule broke
before. If an atom loses one or more electrons, it becomes
positively
charged; this is called a positive ion. If one supplies the
appropriate
energy to the system the atoms will eventually break up into
electrons
and ions. Therefore, we see that by adding enough energy to any
material,
we can eventually produce a gas of electrons and ions.
This last gas of
electrons and ions is called a plasma.
Thus,
we can say that plasma is as a gas
that can
carry an electrical charge. Plasma is a form of matter that exists
when atoms are in an
excited state.
From above we conclude that when we incrase temperature(making hot
pocket ) by that atoms are in very exited state so it become a gas
and after more increas in T ( temperature ) atoms becomes super
exited in form of plasma...
