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 1: Sally's pet lizard makes a weird groaning noise every couple of seconds. She notices that the number of groans per minute is very regular, but increases as the temperature increases. Further observations reveal that the number of groans per minute actually has a linear relationship with temperature over the normal range of temperatures in the lizard's natural environment. So she decides to make use of her lizard as a thermometer. Sally measures that the number of groans per minute at 10.0°C is 12, and the number of groans per minute at 45.0°C is 31. If she measures that the number of groans per minute in the lizard's usual aquarium is 24, what is the temperature in the aquarium, in degrees Celcius? You can check your answer using the Mastering Physics assignment. Math tip: A linear relationship between two quantities X and Y, means that for a change in X (which we usually call AX), the change in Y is given by AY = m AX, where m is some constant. In the range of X where this…

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
