For first day of class:Read parts of Chapter 1 enough to bring to class Schroeder's definitions of a) temperature, b) heat, and c) work.

The 'expiration' date of an assignment is two days after the due date.

• Make an enlightened calculation to find the number of kg of argon in the atmsophere, within10-20% . It's pretty much all Ar-40, coming from K-40 decay, as Wikipedia will tell you. Make sure I can follow how you are doing the calculation.
  
• 1.3, 1.4 p. 5
• 1.6,  p. 6; 1.11  p. 8
• 1.15, p. 8. a) Find the density of air in Albuquerque at 40 F (dawn) and 55 F (late morning). b) Take the balloon diameter to be 60 ft. (Balloons like those in Fig. 1 are launched during the Balloon Festival in Albuquerque, NM in October each year.)
  
• For temperatures of 40 F and 55 F,. find the mass of air inside the balloon when hovering. c) Find the average air temperature inside the balloon with outside air is 40 F (dawn),  at 55 F (late morning).
  

• Prob 1.17 a) and b) p. 9
• Prob 1.17 c) and d), p. 9
• Prob 1.21, p. 14
• Prob 1.24, p. 17
• Prob 1.27, Prob 1.29, p. 20
• Use data on pp 404,5 to out how many mols of propane must be burned to raise the air temperature inside the balloon from 310 K to 320 K, including the air which would leave during the heating (assume all the air stays inside during heating). Write out the stoichiometry, and show the details of the calculation. Look-up of propane combustion will not do. Same balloon as earlier, 60 ft diameter.

• Calculate the heat flow through the walls and ceiling of the SRC for 20 degrees F temperature difference. Take the building to be 27' high and 314' x 208' in footprint. Ignore heat flow through the floor, take 20% window area, 80% other area, R-2 for windows, R-10 for walls, etc. First find the heat flow in BTU/hr, then watts. Determine the heating cost per day, at 10 cents per kwh.
• Prob. 1.34, p. 23
• Prob 1.22 a) through e), p. 14
• In a diesel engine, air is compressed quickly to 1/25 of its original volume. Determine the final air temperature, ignoring the small amout of injected diesel fuel present. Why doesn't a diesel engine need spark plugs?
• Prob 1.62, p. 40. You must make a sketch, showing a boundary at x and another at x+dx, across which heat flows.
  
• Prob 1.70, p.48

• Problem 2.8, p. 59. Let solids A and B have 15 oscillators each, and A and B share a total of 30 energy units.
• Problem 2.10, p. 60. Let solid A have 250 oscillators and B have 150 oscillators, and the two share 80 energy units.

• Problem 6.23, p. 236. Keep adding j values till Z changes by less than 0.1 %
• Problem 6.39, p. 246.  Use Digits = 300 in Maple.  You must get x_min like Schroeder does on p. 246
