Question

where we use compressibility in our daily life​

Answer 1

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 {\displaystyle \beta } 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 opposite of the fraction makes compressibility positive in the (usual) case that an increase in pressure induces a reduction in volume. It is also known as reciprocal of bulk modulus(k) of elasticity of a fluid.
