Rigidity is the ability to resist the change of shape. Compressibility is the strength to reduce the gas to less volume by applying an external force. Fluidity is the ability of liquids and gases to flow. Filling a gas container is to attain the shape of the container with gas. The shape is a definite boundary. Kinetic energy is the energy of motion. Density is the mass per unit volume. In this post, we have provided a comprehensive definition of rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy, and density.

Rigidity, Compressibility, Fluidity, Filling a Gas Container, Shape, Kinetic Energy and Density

The definitions and properties of rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy, and density given are discussed below:

(A) Rigidity: Solids exhibit rigidity, which is the property of matter that makes them capable of resisting a change in shape. As is well knowledge, gases have relatively little in the way of stiffness compared to solids and liquids, which are less rigid than solids.

(B) Compressibility: The ability of a gas to be compressed by an external force into a smaller volume is known as compressibility. Gases are compressible easily as they have wide empty spaces between their particles, whereas solids and liquids both exhibit negligible compressibility and low compressibility.

(C) Fluidity: Liquids and gases exhibit the property of fluidity, which is characterised as the propensity to flow. Less fluidity exists in solids. Both gases and liquids have the ability to alter their form in response to an external stimulus.

(D) Filling a Gas Container: When a gas container is filled, the gas has taken on the shape of the container. As is common knowledge, solids do not require a container to contain them, whereas liquids must. Gases, on the other hand, have the ability to fill containers fully.

(E) Shape: The border is referred to as the form. We all know that liquids and gases lack set shapes and bounds, whereas solids have both defined boundaries and definite shapes. They possess the ability to take on the shape of the container they are housed in.

(F) Kinetic energy: The definition of kinetic energy is the energy of motion, and as particles of matter are constantly in motion, they have kinetic energy. Because of the strong inter-particle forces that hold particles to one another, solids have the least kinetic energy. In contrast, liquids have greater kinetic energy than solids, and gas particles have substantially higher kinetic energies than solid particles.

(G) Density: The mass per unit volume is the definition of density. It speaks to a substance’s capacity for compactness. As a result, solids have a higher density than liquids, whereas gases have the lowest density.
