1. The problem statement, all variables and given/known data When water freezes, it expands about 9.10%. What would be the pressure increase inside your automobile engine block if the water in it froze? The bulk modulus of ice is 2.00 multiplied by 10^9 N/m2. 2. Relevant equations Delta P=-B*(Delta V)/V 3. The attempt at a solution Delta P= 2*10^9*.091 = 1.82*10^8 Pa It says that the answer is within 10% of the correct answer however I dont know if there is a small error that is causing me to be slightly off.
