At atmospheric pressure, pure water boils at 100c, and freezes at 0c. in this problem, we calculate how this changes for seawater. a) use the latent heat of vaporization and salinity to calculate the boiling temperature of seawater at atmospheric pressure. b) at atmospheric pressure, the latent heat of fusion for ice is 6.0kj/mol. use this information to calculate the freezing temperature of water. assume that when the solution freezes, it forms a phase of pure ice. c) in part (a), the boiling temperature is increased by the addition of salt. however, in part (b) the freezing temperature is decreased. using what you know about the entropy of mixtures, explain why this is the case.

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
