### Ch 8.1 Solving work

Posted:

**Mon Jan 15, 2018 10:41 pm**In the textbook page 264, there's a self-test problem 8.1A and I keep getting a different answer than the answer provided.

Water expands when it freezes. How much work does 100. g of water do when it freezes at and pushes back the metal wall of a pipe that exerts an opposing pressure of 1070 atm? The densities of water and ice at are 1.00 and 0.92 , respectively.

My answer: -0.94 kJ

Does anyone know how to solve it? The textbook's answer is -0.86 kJ.
