Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.

QUESTION 35 A syringe (X), forces air, at a high velocity, over a straw (Y). The air in the water chamber (Z) is not moving. Using Bernoulli's Principal, pick the best answer, that describes what will happen to the water in the chamber. Remember that things are always pushed from high pressure areas to low pressure areas. a. The high velocity air at (Y) will have the SAME PRESSURE as the low velocity air over the water at poing (Z), so the water will neither move up or down the straw. b. none of these are true. c. The water in the straw will be forced down into the chamber because the high velocity air at (Y) has a HIGH PRESSURE compared to the air over the water in the chamber at point (Z). d. The high velocity air at point (Y) will have a LOW PRESSURE. As a result, the slow air in the chamber (Z) will have a high pressure, thus forcing water up the straw.
