Question

4. Define the terms:

a) Fluidity b) Compressibility​

Answer 1

Answer:

a.The ability of a substance to flow easily.

b.In thermodynamics and fluid mechanics, compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change. In its simple form, the compressibility β may be expressed as , where V is volume and p is pressure.

Answer 2

Answer:

It is the property as a result of which the particles of any matter come closer on applying pressure. (b) Rigidity. It is the capacity of the particles of a matter to resist a change in shape and size on applying stress. (c ) Fluidity. It is the property as a result of which particles of a matter have tendency to flow.
