2. a) Rigidity- it is a property of shape of the matter whether it rigid or non rigid that means if it is harder or softer.
Compressibility- this property tells us about whether the particular matter is compressible or not.
fluidity-this property tells us if the particular matter flows or not.
b) Rigidity- is the physical property of being stiff and resistance to bending or flowing. Solids are highly rigid. Liquids and gases are not rigid.
Compressibility- is the property of being able to occupy less space. Solids cannot be compressed easily.
Fluidity- is the ability to flow.
filling a gas container- Gases are highly compressible. Thus, large volumes of gases are compressed and stored in containers so that they are easier to store and transport.
shape- Solids have definite shape and retain their shape till an outside force changes its shape. Liquids and gases do not have a definite shape.
Kinetic energy- is the energy possessed by objects by virtue of their motion.
Density- is defined as the mass per unit volume. Density refers to the amount of matter that is present per unit volume.
