What is compressibility ? Write its formula, unit and dimensional form

1.	What is compressibility ? Write its formula, unit and dimensional formula.
Answer» Solution :The reciprocal of the bulk modulus is called compressibility. It is DENOTED by k. It is also DEFINED as the fractional chanage in volume per unit increase in PRESSURE. `k = ((1)/(B)) = (-1)/(Delta p) XX ((Delta V)/(V)) =- (Delta V//V)/( Delta p ) ` Its unit is `N^(-1) m ^(2) or Pa ^(-1)` and dimensional formula `[M^(-1) L ^(1) T ^(2)]`
