Self Test Example 8.1A

Postby Ayona Sengupta » Thu Jan 18, 2018 6:11 pm

I saw this question under the self-test section of example 8.1 in the textbook and I'm a little confused on how we'd use both the densities of water and ice in this question.

Water expands when it freezes. How much work does 100 g of water do when it freezes at 0.0 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 0.0 C are 1.00 gcm3 and 0.92 gcm3, respectively.

Given the mass and density, we can use the equation volume = mass/density for both water and ice to figure out the change in volume. From there, work can be calculated.
