Chapter 19, Problem 13ICA
A phase diagram for carbon and platinum is shown. It is assumed the lines shown are linear, and the mixture has the following characteristics. The endpoints of the division line between these two phases are labeled on the diagram.
■ Below 1700 degrees Celsius, it is a mixture of solid platinum (Pt) and graphite (G).
■ Above 1700 degrees Celsius, there are two possible phases: a Liquid (L) phase and a Liquid (L) + phase (G).
Write a program to determine the phase. The program should ask the user to enter the weight percent carbon and the temperature in degrees Celsius. Call the phases “Pt + G,” “L,” and “L + G,” for simplicity. If the point falls directly on the T = 1700°C line, include the point in the “Pt + G” phase. If the point falls directly on the L, L + Gline, include the point in the “L + G” phase.
Store the phase as text in a variable. The equation of the line dividing the L and L + G phases must be found in the program using polyfit. The program should produce a formatted output statement to the command window. Similar to “For X.XX weight percent carbon and a temperature of YYY degrees Celsius, the phase is PHASE” where x.xx, yyy and PHASE are replaced by the actual values formatted as shown.
The following partial code is designed to implement this program. You are to fill in the missing sections of code as appropriate to complete the program.

The given figure shows the pressure-temperature phase diagram for H2O. Apply the Gibbs phase rule at points A,B, and C, and specify the number of degrees of freedom at each of the points, that is, the number of externally controllable variables that need to be specified to completely define the system.
Under extreme pressures, even very familiar substances can form unusual solid phases. Below is the phase diagram for H2O, expanded to include those phases that are found at high pressures. The following two questions refer to that diagram.
For the first question, select every statement that is true about the relative densities of different phases of water.
a. Solid phase ll is more dense than phase V
b. Solid phase ll is more dense than phase lll
c. Solid phase Vl is more dense than liquid water
d. Solid phase Vll is more dense than phase Vlll
e. "Traditional" ic (solid phase lh) is more dense than liquid water
