The volume change of a solid copper cube 20 cm on an edge, when subjected to a pressure of 14 MPa is
(Bulk modulus of copper 140 GPa)

Explanation

Here, `L = 10 cm = 0.10 m, p=7 xx 10^(6)Pa, B =140 Gpa = 140 xx 10^(9) Pa`
As, `B =(pV)/(Delta V) or (Delta V) = (pL^(3))/(B) = ((7 xx 10^(6)) xx (0.10)^(3))/(140 xx 10^(9)) = 5 xx 10^(-8) m^(3) = 5 xx 10^(-2) mm^(3)`.
