Air at 320 k saturated with water vapor is dehumidified by cooling to 285 k and by condensation of water vapor. air leaving the dehumidifier saturated at 285 k is mixed with a part of the original air, which has bypassed the dehumidifier. the resulting air stream is reheated to 320 k. it is desired that the final air contain water vapor not exceeding 0.03 kg/kg of dry air. calculate: 2) (a) the dry air bypassed (in kg) per each kg of dry air sent through the dehumidifier. (b) the water vapor condensed in the dehumidifier (in kg) per 100 m2 of air sent through it. (c) the volume of final air obtained per 100 m3 of air passed though the dehumidifier data: total pressure of system-1 atm or 101.3 kpa vapor pressure of water at 285 k- 1.4 kpa vapor pressure of water at 320 k- 10.6 kpa 3

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.

Describe what happens to the molecules as water goes from ice to liquid to vapor. be sure to explain what happens to the temperature during the phase changes.
