Question

what is compressibility​

Answer 1

Answer:

Compressibility is the measure of a liquid's relative volume change when the pressure acting on it changes. Compressibility is related to thermodynamics and fluid mechanics. It is denoted by beta “B”. The Compressibility of a fluid depends on adiabatic or isothermal process.

Answer 2

Answer:

In thermodynamics and fluid mechanics, compressibility (also known as the coefficient of compressibility[1] or isothermal compressibility[2]) is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. In its simple form, the compressibility β may be expressed as

{\displaystyle \beta =-{\frac {1}{V}}{\frac {\partial V}{\partial p}}},

where V is volume and p is pressure. The choice to define compressibility as the negative of the fraction makes compressibility positive in the (usual) case that an increase in pressure induces a reduction in volume.
