How to draw a phase diagram?
- Draw a vertical line on the phase diagram at the appropriate composition and determine the point at which it intersects the liquid composition line, which is marked in red. (b) Draw a horizontal tie line and deduce the compositon of the vapour from the blue line.
What is the liquid phase?
- The liquid phase exists at high pressure and high temperature, and is therefore represented by area B. Standard ambient temperature and pressure (SATP) corresponds to 1 atm = 1.0325 bar and 25 ?C = 298 K. This point falls within area C, which corresponds to the gas or vapour phase. The phases that occur depend upon the pressure of the sample.
What are the phases of a substance?
- The phases that occur depend upon the pressure of the sample. At 35 bar, the substance exists as a liquid (area B) at 250 K, but becomes a solid (area A) at 150 K. However, at 5 bar, the substance exists as a vapour (area C) at 250 K, and sublimes to become a solid (area A) at 100 K.
How do you find the equilibrium between two solid phases?
- The equilibrium between two solid phases is described by the Clapeyon equation. Since you have the two densities then the volume change for the phase Use Equation 17.11, which shows how the electrostatic potential energy between two charges varies with separation. 2 PE=40 0. Mg2+ ions 16.
