Q. 3: (L.O.6.1) Choose the incorrect statement about osmotic pressure: A. As solvent moves across the membrane, the fluid levels become uneven. B. Osmotic pressure is the pressure required to stop osmosis. C. The osmotic pressure is proportional to temperature. D. Osmosis is the movement of a solute from high to low solute concentration.

3. Consider the following weighted graph: San Seattle 808 Francisco Las Vegas 2060 2257 1780 Oklahoma City 272 Phoenix Los Angeles 1440 792 12 Minneapolis 1217 Milwaukee 949 Chicago 948 1614 New York 811 City 237 Washington D.C. 1423 517 Dallas 'New Orleans Miami Assume Phoenix is the start node and Chicago is the destination node. Trace the contents of the Distance Destination, Path, and Included arrays as Dijkstra shortest path algorithm runs to generate the shortest path between the start and the destination. Provide only the final states of the arrays.
Question 3 (20 points) Write a program that print proper air control messages according to temperature and humidity. The user should provide the values for the temperature and humidity. Remember that the temperature doesn't have to be whole numbers. The program prints the following message depending on the following: • For temperature below 68, it prints "Turn on the heater." • For temperature between 68 and 79 (including 68 and 79), • If the humidity level is below 0.5, it prints "Open the windows to get fresh air." • Otherwise, it prints "Turn on the dehumidifier." • For temperature above 79, it prints "Turn on the cooler."
(4 points) Consider the density of states and statistical factor for particles governed by Bose-Einstein statistics, $g_{BE}(E)$ and $F_{BE}(E)$, respectively. Combined, they yield the energy distribution function for bosons according to $n_{BE}(E) = g_{BE}(E) \times F_{BE}(E) = \frac{8\pi L^3}{h^3c^3}E^2\frac{1}{e^{E/kT} - 1}$ (9.54) From this energy distribution, determine the mean energy per unit volume $E/L^3$ at $T = 0$ and $T = 300 K$. A) 0 eV/nm³ and 2.21 x $10^{-89}$ eV/nm³ B) 0 eV/nm³ and 5.36 x $10^{-6}$ eV/nm³ C) 0 eV/nm³ and 3.35 x $10^{-14}$ eV/nm³ D) 0 J/m³ and 3.35 x $10^6$ J/m³ E) 0 eV/nm³ and 8.14 x $10^{69}$ eV/nm³ Ans:C
