Comment on the Following Properties: (a) Rigidity (B) Compressibility (C) Fluidity (D) Filling a Gas Container (E) Shape (F) Kinetic Energy and (G) Density

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 container by gas. Shape is a definite boundary. Kinetic energy is the energy of motion. Density is the mass per unit volume

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

The properties given are discussed below.

(A) Rigidity:

• Solids exhibit rigidity, which is the property of matter that makes it 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 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.
