Materials Chemistry for Engineers 1. In the van der Waals corrections to the Ideal Gas Law: (P + a/V2)(V – b) = nRT (a) What do a and b correct for from the Ideal Gas Law? (b) How would one determine a and b experimentally? Describe a proposed experiment and data analysis method for your experiment. 2. (a) What are the assumptions of the Ideal Gas Law? How did van der Waal modify these assumptions to come up with his equation of state? (b) what is an equation of state, in general? Describe in your own words. 3. Given the following data: Material a b_____ (l2.atm/mole2) (l/mole) N2 1.39 0.03913 NH3 4.17 0.03107 Aniline 26.50 0.1369 Benzene 18.00 0.1154 (a) Plot P vs. T for each gas using the van der Waals equation of state. Assume that you have a 1 liter volume and 1 mole of gas and plot the temperature on the x-axis from room temperature to 1400 K (pressures should range from about 0 atm to about 120 atm, depending on the gas). Plot the Ideal Gas Law with the other data on one plot. Are the interactions between molecules attractive or repulsive at low temperature? How do you know? What is happening with the gases at high temperature? Is one of the gases different from the others at 1400 K? (b) Discuss the nature of the intermolecular interaction that creates the deviation from ideality for each material. Are there induced dipole-induced dipole interactions, iondipole interactions, etc. for each of the different gases? Draw their chemical structures. 4. Ethane (CH3CH3) and fluoromethane (CH3F) have the same number of electrons and are essentially the same size. However, ethane has a boiling point of 184.5 K and fluoromethane has a boiling point of 194.7 K. Explain this 10 degree difference in boiling point in terms of the van der Waals forces present. Bonus, what is the size of each molecule? Show your calculation/sources.

Consider the problem of implementing insertion sort using a doubly-linked list instead of array. Namely, each element a of the linked list has ?elds a.previous, a.next and a.value. You are giving a stating element s of the linked list (so that s.previous = nil, s.value = A[1], s.next.value = A[2], etc.) (a) Give a pseudocode implementation of this algorithm, and analyze its running time in the T(f(n)) notation. Explain how we do not have to “bump” elements in order to create room for the next inserted elements. Is this saving asymptotically signi?cant? (b) Can we speed up the time of the implementation to O(n log n) by utilizing binary search

The second task : Tutorial Topic 7 – MIS (to be completed over 2 weeks) Describe a decision support system whose purpose is to help you decide which accommodation would be best for you whilst at college next year. Hints: You will need to decide on the factors that will influence your decision, and decide on any weightings that may apply to these factors. You will also need to supply a formula to derive ‘the best solution’, making sure it can support ‘what if’ features. Factors you might consider – affordable rent values, flat or house, sharing (how many others), location, personal circumstances etc.

What type(s) of intermolecular forces exist between HBr and CH2F2? A) dispersion forces only B) dispersion forces and ion-dipole C) dispersion forces and dipole-dipole D) dispersion forces, ion-dipole, and dipole-dipole E) None. Since both are gases at room temperature, they do not interact with each other.

Read: http://xnet.kp.org/permanentejournal/winter03/leader.html This article talks about physicians as leaders. It is written by a physician for physicians, so it provides insight into how doctors think of themselves in leadership. How can you use this understanding of doctors and leadership in managing your own healthcare facility? After all, the organizational chart shows the board of directors and CEO at the top, but physicians are just as important in leading any hospital or clinic. How will you integrate physicians as leaders in your own organization?
