28. QC S Review. Figure P1.28 shows students studying the thermal conduction of energy into cylindrical blocks of ice. As we will see in Chapter 19, this process is described by the equation Q_ krd (Th – T.) At 4L For experimental control, in one set of trials all quantities except d and At are constant. (a) If d is made three times larger, does the equation predict that At will get larger or get smaller? By what factor? (b) What pattern of proportionality of At to d does the equation predict? (c) To display this proportionality as a straight line on a graph, what quantities should you plot on the horizontal and vertical axes? (d) What expression represents the theoretical slope of this graph?

58. A retired partner from a large brokerage firm hasone million dollars available to invest in particularstocks or bonds. Each investment’s annual rate ofreturn depends on the state of the economy in thecoming year. The file P09_58.xlsx contains thedistribution of returns for these stocks and bonds asa function of the economy’s state in the coming year.As this file indicates, the returns from stocks andbonds in a fair economy are listed as X and Y. Thisinvestor wants to allocate her one million dollars tomaximize her expected value of the portfolio oneyear from now.a. If X 5 Y 5 15%, find the optimal investment strategy for this investor.

An ideal gas, at pressure 4.9 atmospheres, in a volume 1.1 m3 and at a temperature of 308 K, is compressed into a lower volume 0.44 m3, at a pressure of 6.26 atmospheres. What is the new temperature, in K with two digits of precision?
A bag of frozen vegetables with temperature 32◦F is placed in a 75◦F room. After 20 minutes, the temperature of the vegetables has risen to 41◦F. Using this information, find an exponential formula for the temperature of the vegetables where time is measured in minutes. To find the exponential formula, transform the temperature into a new variable for which the problem can be solved as an exponential growth/decay problem. Then find the formula in that variable and transform back to temperature. Based on the formula, what is the temperature of the vegetables after 45 minutes?

In lab we determined the specific heat of several cubes of metal. One of those cubes was lead which had a specific heat of 0.13 J/g oC. Let’s imagine a thought experiment where we drop a 100 g piece of lead off the roof of a 10 meter tall building. A. How much will the temperature rise for the lead when it hits the ground? B. How much potential energy does the lead have at the top of the roof? C. How much kinetic energy does the lead have just prior to striking the ground? Assume that the mechanical energy is conserved and transferred to the lead to be thought of as heat, Q. Using Q = mc(T-To), solve for (T-To), the change in temperature.
