Question

The density of water at 0°C is very nearly 1000 kg/m³ (it is actually 999.84 kg/m³), whereas the density of ice at 0°C is 917 kg/m³. The bulk modulus of ice is 2.20 × 10⁹ Pa.    Calculate the pressure, in pascals, necessary to keep freezing water from expanding, neglecting the effect such a large pressure would have on the freezing point. (This problem gives you only an indication of how large the forces associated with freezing water might be.)  

Answer 1

doesn't need to consider sign here pressure indicates ,the pressure need to keep ice from expanding
