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.

• A constant-volume gas thermometer (pp 4-6) has a pressure of 50,000 Pa at 100 C.  Find its pressure at 50 C and at 25 C.
  
• For a 'Galileo Thermometer' find the conditions for a partly filled glass sphere (OD = 2.00 cm) to float in the surrounding liquid
• specific the liquid in the enclosing tube
• type of glass in the sphere
• thickness of the glass sphere
• specific liquid half-filling the sphere
• weight W hanging from the sphere
• Include a numerical calculation to show this arrangement is neutrally buoyant at a given temperature (say, 20 C)
• Give references for the information you are using
  
• 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).
  

• If a NFL football is inflated to 12.5 psi at temperature T1 & cooled to 45 degrees F, where it has a pressure of 10.5 psi, find temperature T1, in degrees F 
• 1.18, 1.19 p. 13
  
• 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.
• Galileo thermometer: two spheres 2 cm OD ,one neutrally buoyant at 20 C and the other neutrally buoyant at 25 C. Spell out the liquid in the container, internal liquids and how much, Thickness, type of glass,  dangling mass.
  

• A thermos bottle has an evacuated stainless steel inner vessel, which we take to be a cylinder 0.28 m long, and radius 0.05 m.
• find the heat capacity in j/ deg C for a water-filled thermos (from C_water = 1 cal/g- deg C)
  
• use the information on pp. 302-305 to calculate the rate of temperature change (degrees/sec) for water at 120 F and the container at 70 F
• take the emissivity of the steel to be 0.12,
  
• Now assume a 1-inch long 'neck' of stainless steel (1/2 mm thick) radius 0.050 m connecting the inner vessel to the outer one. Work out the conductive heat flow (W) between  inner and outer containers at a temperature difference of 120 - 70 degrees F ( k = 14 W-m-K ). How much does the temperature drop from 120 F in 7 hours due to both mechanisms.
