Q. Water exists as a _____________ at 700 mmHg and 50 °C. Q. What phase change (s) may occur at pressures below 4.58 mmHg? Q. The pressure is increased on a sample of water at 0 °C from 0 mmHg to 800 mmHg. In order, what changes occur? Q. Based on this phase diagram, which state is the most dense? Q. Based on its phase diagram, which is the ...

While this may seem like an obscure question, the MCAT specifically requires you to know the shape of the water phase diagram. Unique to only a few molecules, the solid phase in our diagram is less dense than the liquid phase, meaning that the solid/liquid phase line has a negative slope (this can be seen as segment AD in the above image).

a) Melting temperatures of various phases. b) Temperature range for solidification. c) Equilibrium solid solubility. d) Purity of materials. View Answer. Answer: d. Explanation: A phase diagram is a graphical representation of the phases present in the system of materials at various temperatures, pressures, and compositions.

as axes are called phase diagrams. DEF. A phase diagram (or equilibrium diagram) is a diagram with T and composition as axes, showing the equilibrium constitution. The phase diagram of an alloy made of components A and B, for all combinations of T and X B, defines the A-B system. Binary systems have two components, ternary systems three, and so on.
