Question

comment upon the following rigidity,compressibility, fluidity,filling a gas container,shape,kinetic energy and density

Answer 1

Rigidity; rigidity means the hardness and we cannot break down the rigid subsrance.
Compressibility; A property of matter of compressing something.
Fluidity; shows that how much capacity a substance gas to flow.
Filling a gas container; The particles if gas are far away from each other and contains pressure on the walls of the container.
Shape; shape means size, angle, etc.
kinetic energy; when we increase the temperature, the smell that we get far away is due to the kinetic energy.
Density; It shows how dense or heavy and light that substance is.

Answer 2

Answer:

 

$\underline{\underline{\bf Rigidity :}}$

It is the property of the solids to maintain shape against external force.

$\underline{\underline{\bf Compressibility:}}$

It is the property of gases. On applying high pressure, the volume of the gas decreases.

$\underline{\underline{\bf Fluidity :}}$

It is the property of the liquid and gas by which they have a tendency to flow.

$\underline{\underline{\bf Filling \:\:a \:\:gas\:\: container :}}$

When a denser gas is transferred into another empty container, it spreads and occupies the whole volume of the empty container replacing the air due to negligible interparticle force of attraction.

$\underline{\underline{\bf Shape :}}$

It is the property of the solids. Outer surfaces of a solid produce a certain shape.

$\underline{\underline{\bf Kinetic \:\:energy :}}$

The constituent particles of a matter are not stationary. They are found in constant motion. The particles of gases have maximum kinetic energy because their particles move at high speed.

Kinetic energy,

$\bf K.E = \frac{1}{2}mv^{2}$

[where 'm' is the mass of the particle and 'v' is the velocity of the particle]

$\underline{\underline{\bf Density :}}$

It is the property of a matter. It is defined as the mass per unit volume.

$\bf Density=\frac{Mass}{Volume}$
