Question

) Tabulate the differences in
the characterisitcs of states
of matter
(b) comment upon the following rigidity, compressibility,fluidity,filling a container,shape, Kinetic energy and density​

Answer 1

Answer:

Explanation:

ANSWER:-

SOLIDS:-

• Rigid or hard Due to high Cohesive force or Inter molecular force
• Cannot be Compressed
• It is not a fluid
• It is fixed on it's shape ; does not fill a container
• Fixed shape
• Very low Kinetic energy
• High density

LIQUIDS:-

• Not a rigid due to loosely packed particles
• Is very less compressible
• It indeed is a fluid
• Fills a container by taking it's shape depending upon how much to fill
• No fixed shape
• Medium Kinetic Energy
• Medium to low density

GASES:-

• Not rigid due to negligible force of attraction
• Very much compressible
• It is a fluid
• Fills the whole container
• No fixed shape
• High kinetic energy enables to move
• Low density

Answer 2

${ \huge{ \bf{ \underline{ \underline{Question}}}}}$

1- Tabulate the differences in

the characterisitcs of states

of matter.

2-comment upon the following rigidity, compressibility,fluidity,filling a container,shape, Kinetic energy and density.

${ \mathtt{ \green{ \underline{ \underline{Answer \: 1}}}}}$

SOLID:-

• Definite mass, volume, and shape.
• Short Intermolecular distance.
• Strong Intermolecular Forces.
• The constituent particles remain fixed at their positions and can only oscillate about their mean positions.
• Solids are incompressible and rigid.
• High Density.

LIQUID:-

• Liquids do not have fixed shapes.
• Liquids have definite volume.
• Liquids have fluidity and not rigidity.
• Kinetic energy of the particles in the liquid state is more than in the solid state.
• Particles in the liquid state can easily diffuse.

GAS:-

• Gases have neither definite shape nor definite volume. They expand to the size of their container.
• Gases are fluid, and flow easily.
• Gases have low density, unless compressed.
• Gases diffuse (mix and spread out) and effuse (travel through small holes).

Rigidity:-

It is the strongest force of attraction between particles and this property makes the solid rigid. Rigidity gives the perfect shape to solids, the particles in the solid are tightly packed. Solid does not get deformed easily by applying extra pressure.

Compressibility:-

Compressibility is mostly observed in gases. A lot of space between particles, a gas can be compressed to a higher extent. Solids have the least compressibility and liquids have little compressibility because of the least space between their particles.

Fluidity:-

The ability to flow is called fluidity. The less force of attraction and more space between particles makes the liquid and gas to flow easily. Fluidity is not observed in solids.

Filling of a gas container:-

Liquids do not fill a gas container completely, but gases fill the gas container completely in which it is stored. A gas can move in all the directions hence it fills the container completely.

Shape:-

Solids have a fixed shape. Liquid and gas occupy the shape of the container in which they are stored. This is due to the less force of attraction and more kinetic energy between the particles of liquids and the negligible force of attraction and highest kinetic energy between particles of gas.

Kinetic energy:-

The kinetic energy of particles of solid is the minimum. They only vibrate at their fixed position. The kinetic energy of particles of liquid is more as compared to solid. But they can slide above one another. The kinetic energy of particles in a gas is maximum.

Density:-

Density is defined as the mass per unit volume of a substance. The density of solid is highest, then comes liquid, and last comes the gases.
