Question

Comment upon the following:
rigidity, compressibility,
fluidity, filling a gas
container, shape, kinetic
energy and density.
reasons​

Answer 1

Explanation:

rigidity: the tendency of a substance to maintain its shape when subjected to outside force

compressibility :

the matter has intermolecular space between its particle the external force applied on the matter can you bring this particles closer this property is all compressibility gas and liquids are compressible .

fluidity: the tendency of particle to slow it's called fluidity .liquids and gases flow .

shape: solids have maximum intermolecular force and definite shape and liquids and gases takes this shape of container in which they are filled.

kinetic energy : the energy process for particles due to their motion is called Kinetic energy . molecules of gases hybrid randomly so they have maximum kinetic energy .

density: it is defined as mass per unit volume in the solid have highest density

Rigidity→ It is the property of matter to maintain its shape even if external forces work and the solids show this property.

Compressibility → It is the property of matter to allow compression under high pressure and the gases show this property.

Fluidity → It is the property of a substance to easily flow and allow change in its shape under external forces and this property is exhibited by both liquids and gases.

Filling a gas container → Gases can be compressed easily hence they can be filled within a vessel at high pressure. This property of gases allows their convenient filling into a small container or cylinder and that also in a large volume. It also allows their easy transport from one place to the other e.g. CNG.

Shape→ According to the type of matter shape differs depending upon location of particles like Solids have definite shape while Liquids acquire the shape of their container and gases as such don’t have any shape.

Kinetic energy → It is the kind of energy present in an object when it is under motion as the particles of that object/matter are continuously moving therefore matter has kinetic energy. However greater is the movement more will be the kinetic energy and vice a versa i.e. solid < liquid < gas

Density → Mass per unit volume of a substance/matter is known as its density i.e. density = mass/volume
