CHEN 3101 Chapter Notes - Chapter 3: Heat Capacity Ratio, Compressibility Factor, Dome A
Document Summary
Phase refers to a quantity of matter that is homogenous throughout in both chemical compositions and physical structure. Pure substance a substance that is uniform and invariable in chemical composition. A pure substance can exist in more that one phase, but its chemical compositions must be the same. State principle a general rule for determining the number of independent properties required to fix the state of a system. Simple compressible systems a system of commonly encountered pure substances, such as water or a uniform mixture of non-reacting gases. For a simple compressible system, specification of the values for any two independent intensive thermodynamic properties will fix the values of all other intensive thermodynamic properties. 3. 2 p-v-t relation p-v-t surface the graph of the function p = p (t,v) Two phase regions located between the single-phase regions, where two phases exist in equilibrium: liquid vapor, solid-liquid, and solid-vapor.
