11 File Upload 10 points A piston-cylinder device contains 8 kg of water at 120 °C with a quality of 65 percent, the temperature of the surroundings remains constant at 200 °C. This water undergoes two processes as follows: State 1 to state 2: Heat is transferred to the water in a constant pressure process until all of the water is just vaporized. During this process, the temperature is kept constant. State 2 to state 3: The water undergoes an adiabatic, reversible process (i.e. not at constant pressure) until the pressure is 10 kPa. A. Sketch these processes with respect to the saturation lines on a single T-s diagram. B. Determine the heat transferred to the water in the first process (Q1-2), in kl. C. Determine the work done by the water in the second process, (W2→3) in kJ. D. Determine the total entropy generated during the complete process from state 1 to state 3, in kJ/K.

6.2. Concentration Pulse. Suppose that $N_0$ particles of dye are released at time $t = 0$ in the center (at $x = 0$) of a fluid contained within an essentially one-dimensional pipe, and the dye is allowed to diffuse in both directions along the pipe. The diffusion constant $D = 8^2/2$. At position $X(t)$ and time $t$ the density of dye particles is the product $N_0p(x, t)$, where $p(x, t)$ is the probability density of a single dye particle with initialization $X(0) = 0$. An observer at position $x = x_1 \neq 0$ sees the concentration of dye increase to a maximum value and then decay away. See figure 6.4. At what time does the concentration peak pass the observer?

A 0.487 g sample of a metal, M, reacts completely with sulfuric acid according to the reaction M(s) + H$_2$SO$_4$(aq) $\rightarrow$ MSO$_4$(aq) + H$_2$(g) A volume of 225 mL of hydrogen gas is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 1.0079 bar and the temperature is 25 $^\circ$C. The vapor pressure of water at 25 $^\circ$C is 0.03167 bar. Calculate the molar mass of the metal. molar mass: 6.379 g/mol

Consider a configuration of three infinite parallel plates A, B and C. The distance between the plates is L meters. Plates A and C carry a charge density of Q Coulomb per square meter, while B has -Q Coulomb per square meter. Find the electric field outside the parallel plates, in the regions between the parallel plates. Calculate the potential at any point as a function of the distance from the central plate B.
