The change ∆V in the volume V of some water when the pressure on the water increases
by ∆p is given by the expression
∆p = 2.2 × 10
9
∆V
V
,
where ∆p is measured in pascal.
In many applications, water is assumed to be incompressible.
By reference to the expression, justify this assumption.

plz explain the answer.
