Two canisters A and B each contain 0.20 mol of a diatomic gas at 400 K and a pressure of 405300 Pa. A expands isothermally and B adiabatically until the pressure of each is 303975 Pa. [Hint: for a diatomic gas Cv = (5/2)R.] (1) Sketch both processes on a single PV-diagram. (2) What are the final temperature and final volume of each canister.

Thermodynamics T-11 All air is removed (vacuumed) from a 2 liter closed container that contains 200 ml of Liquid A and 600 ml of Liquid B at a temperature of 20C. At this temperature Liquid A has a density of 0.825 g/ml and vapor pressure of 25 kPa. Liquid B has a density of 0.750 g/ml and vapor pressure of 15 kPa. What is the mol fraction of vapor from Liquid A in the head space above the liquid surface? A) .25 B) .38 C) .63 D) .75

As you know, property diagrams are an important tool used in the study of engineering thermodynamics. In this problem, you will practice using the T-s diagram in conjunction with currently-more-familiar property diagrams. For each part below, sketch T-s, T-v, and P-v diagrams. Clearly indicate the initial and final states, the values of the relevant intensive properties, and the process path on each diagram. Figure 7-11 in your textbook might be helpful in deciding the curvature of some of the process paths. a) Water is taken isobarically from a saturated liquid at 275 kPa to a final state with a quality of 65%. b) Water, initially at 2 MPa and 500degrees C, in a rigid tank eventually comes to thermal equilibrium with the surroundings at 100degrees Cc) Refrigerant-134a is compressed isobarically from a saturated vapor with h=256.22 kJ/kg to a final temperature of 0degrees C

Pre-lab 8: Cold Engine The experimental setup for this week's lab consists of a syringe connected to a metal can (reservoir), a cold bath (water - ice mixture) and a "hot" bath (water at room temperature). A schematics of the syringe - reservoir system is shown below. Plunger of mass m Filled with gas (air) Syringe of volume Vcor VH - Volume Vo includes tube + Metal can -Metal can submerged in water of temperature Тс or TH. Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.

By writing E and S as functions of T and P, obtain the following expressions for the differentials dE and dF: dE = (CP-PVb)dt + V(kb-bT)dP and dF = -(PVb+S)dT+PVkdP. β and κ are the isobaric thermal expansion coefficient and the isothermal compressibility, respectively.

Explain in words and/or equations the differences and/or relation-ships between the following: (Image offers symbols in a clearer fashion)(a)  Gi_bar, μi, Gi (Molar gibbs free energy, chemical pontential, gibbs free energy)(b)  G^R and G^E (Gibbs residual and Gibbs excess property [ie. Excess = molar vs ideal mixture])(c)  f_i and P (fugacity and pressure)

A sample of oxygen (O2) of mass 1 g is contained in a 1000 cm3 volume at an initialtemperature of 288.15 K. Take the oxygen to be a perfect gas, with a molar mass of32 ×10−3kg/mol and a constant specific heat ratio of 1.40.(a) Compute the density (kg/m3) and pressure (kPa) of the gas at the initial state.(b) Calculate the changes in pressure (kPa) and internal energy (J), when the systemundergoes a process that produces a final volume of 60 cm3 and a final temperatureof 400 K.
