define rigidity , compressibility, fluidity, filling of a gas container , shape, kinetic energy and density
Answers
Answer:
Rigidity is defined as the property exhibited by the solid to change in its shape. That is when an external force is applied to the solid material, there won't be any change in the shape. This shows that the particles are closely packed and the attraction between these particles are very strong.
Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together.
A continuous, amorphous substance whose molecules move freely past one another and that has the tendency to assume the shape of its container; a liquid or gas is fluidity
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.
Molecules have shapes. There is an abundance of experimental evidence to that effect—from their physical properties to their chemical reactivity. ... The basic idea in molecular shapes is called valence shell electron pair repulsion (VSEPR).
the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes
Density, mass of a unit volume of a material substance. ... The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

Explanation:
the quality or state of being rigid. 2 : one that is rigid (as in form or conduct).
It is the property as a result of which the particles of any matter come closer on applying pressure. <br>
It is the property as a result of which particles of a matter have tendency to flow.
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.
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.
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.
