The density of water at 0 C is 999.8 kg/m^3 while that of ice at 0 C is 917.0 kg/m^3. What is the pressure generated by expanding ice as it freezes in a biological cell whose major component is water? Assume the cell to be a sphere of radius 5 micrometres.
I have started this question but I do not know how to complete it. I can't picture the right expression that will yield pressure with respect to a phase change.
P = F/A
Density = mass/volume
where L is the heat of transformation
