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

100%

An insulated rigid tank contains a saturated liquid-vapor mix of water initially at a pressure of 100 kPa. The mass of the mixture is 5 kg, but only 75.6% of the total mass is liquid. An electric resistance heater is turned on within the tank until all the water has just vaporized. The heater power is a constant 2.2 kW. Hint: you will not need to interpolate to find the solution to part (b).

**Diagram Explanation:**
The diagram shows a cross-section of an insulated tank with a liquid-vapor mixture. The tank appears to be rectangular, with an electric resistance heater submerged in the liquid portion. The blue color indicates the liquid water portion, and the liquid level is below the top of the tank.

*Note: quantities shown in the figure are not necessarily to scale.*

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?
N = 0 An insulated tank of volume 10+(10+N)/25 m and with a valve was filled with perfect tri- atomic gas at pressure 10 bar, where N is equal to the last two digitals in your student's ID number. Initially the valve was closed. A paddle wheel was mounted inside the tank and was run by 20 kW engine. The paddle wheel was turn on and at the same time the exit valve was opened. The gas temperature was constant though the whole process (due to very slow flow) and equal to 300 K. Calculate the time needed to decrease the pressure in the tank to 5 bar.

Mr Zul operates a hot plate. He places a closed, rigid container of volume 0.5 m3on the hot plate. Initially, the container holds a saturated mixture with quality ofvapour of 0.5, at a pressure of 100 kPa. After heating, the pressure in the containerincreases to 150 kPa.a) Calculate the mass of vapour at the initial and final states (in kg).b) If heating is allowed to continue, find the pressure (in kPa) when thecontainer holds only saturated vapour.c) Sketch the T – v diagram for this system.
