SUMMARY
The pressure increase inside an automobile engine block due to the freezing of water can be calculated using the formula Delta P = -B * (Delta V) / V, where B represents the bulk modulus of ice, measured at 2.00 x 10^9 N/m². The calculated pressure increase is 1.82 x 10^8 Pa, which is within 10% of the expected answer. The expansion of water upon freezing is approximately 9.10%, leading to a significant pressure change in confined spaces such as engine blocks.
