2. Properties of Solid 1. A solid has a definite volume and
definite shape. The intermolecular force of attraction is very
strong. The molecules are strongly held and arranged in order. 2. A
solid is rigid and cannot be compressed easily. Molecules are
closely spaced and the intermolecular separation is very small
which cannot be reduced further. 3. A solid does not flow and can
be stored in a container. Intermolecular fore of attraction is so
strong that molecules do not flow and leave the surface of the
solid. 4. A solid on hating usually changes into its liquid state.
Heating provides sufficient energy to molecules to overcome the
intermolecular force of attraction. Intermolecular separation
increases, changing the solid into liquid.
3. Properties of Liquid 1. A liquid has a definite volume.
Intermolecular force of attraction is just strong enough to confine
the molecules in a definite space. 2. A liquid has no definite
shape and acquires the shape of the container. It can flow from a
higher lever to a lower level. 3. A liquid is compressible.
Distance between the neighboring molecules is larger in a liquid
than in a solid. 4. A liquid can diffuse into another liquid, but
this is much slower as compared to the diffusion of gases.
Molecules move faster in a liquid than in a solid but slower as
compared to the molecules of a gas.
4. Properties of Gas 1. A gas has no definite shape or volume
of its own. It acquires the shape of the container. 2. A gas is not
rigid and is easily compressed. Intermolecular separation is very
large in gaseous state which can be decreased by applying pressure.
. 3. A gas on cooling changes into liquid state. Cooling reduces
intermolecular separation and increase intermolecular force of
attraction. 4. A gas can flow in all directions. It requires a
vessel closed from all sides. 5 . A gas can diffuse into another
gas. Molecules in a gas move very fast. Hence the speed of
diffusion is very large.

8. Plasma- Everything on Earth can be explained in terms of 4
states (phases) of matter- solid, liquid, gas. Some scientists
designate plasma as a fourth state of matter. At very high
temperatures, matter becomes a plasma. Major physical
characteristics define each state and primarily concern volume and
shape. The Molecular Theory of Matter, Theory of Heat and the
Molecular Attraction Force affect the states of matter. The
Molecular Theory of Matter and the Theory of Heat state that
molecules are in constant motion. Properties describe matter.
