The definition of a phase, as given by SB&VW, is ``a quantity of matter that is homogeneous throughout.'' Common examples of systems that contain more than one phase are a liquid and its vapor and a glass of ice water.

13 Απρ 2022 · University of Maryland. As explained in Sec. 8.2, a phase diagram is a kind of two-dimensional map that shows which phase or phases are stable under a given set of conditions. This section discusses some common kinds of binary systems, and Sec. 13.3 will describe some interesting ternary systems.
In the present experiment, the phase changes that occur in a two-component mixture will be investigated. The three common phases of matter are the solid, liquid and vapor states.
12 Ιουλ 2019 · Learning Objectives. To calculate the energy changes that accompany phase changes. We take advantage of changes between the gas, liquid, and solid states to cool a drink with ice cubes (solid to liquid), cool our bodies by perspiration (liquid to gas), and cool food inside a refrigerator (gas to liquid and vice versa).
A simplified “phase diagram” is shown below in Figure 1, where the phase(s) of the system is plotted against temperature (y-axis) and composition (x-axis). The melting points of the two pure components (T m,A for A and T m,B for B) are also noted.
11 Αυγ 2009 · From your data, generate the solid-liquid phase diagram for your system and determine Δ fus H and the melting point for the two pure substances at 95% confidence. Determine the eutectic temperature and composition, along with your best estimate of the uncertainties for these values.
A. Purpose - The objective of this experiment is to construct a liquid and vapor phase diagram of a binary or two-component system containing water and propanol. In order to determine the phase diagram, the temperature of the system must be measured during the experiment and the specific mole fractions must be obtained.
