I've done this problem so many times and I can't get the right answer. Can someone please write out the solution?
Water expands when it freezes. How much work does 100. g of water do when it freezes at 0 deg. C and pushes back the metal wall of a pipe that exerts an opposing pressure of 1070 atm? The densities of water and ice at 0 deg. C are 1.00g/cm^3 and 0.92g/cm^3, respectively.
The answer is w = -.86 kJ.
