## Homework Statement

When water freezes it expands by about 9.00%

What pressure increase would occur inside your automobile engine block if the water in it froze?

( The bulk modulus of ice is 2.00*10^9 N/m^2

## Homework Equations

Bulk modulus = ΔPressure/(ΔVolume/Initial Volume)

## The Attempt at a Solution

Let V initial= V, V final = 1.09 V

ΔP= 2*10^9*(0.009/1)

I know that somehow V initial must be 1.09 in order to get the correct answer. I just don't understand why ?
