Question

Define compressibility. Write it's SI unit

Answer 1

Compressibility it's the relative volume change of a fluid in response to the pressure change.

SI unit - m2/n

Answer 2

It is defined as the reciprocal or of modulus of elasticity the si unit of compressibility is $m^{2/n}$.

Detailed answer

Also defined as the reciprocal of bulk modulus, the compressibility of any medium or object is the fractional change that occurs in its volume, ie per unit increase in its pressure.

• The unit used to define compressibility is $n^{-1} m^{-2}$
• The unit can be abbreviated as Newton per meter square
• The best example for defining compressibility is the working of a piston in a closed container and its operation as it exhibits compressibility.
