New page

1) How Much Air Can you blow into a PVC Pipe?
:As an in class demonstration/activity, i asked the students to determine how much air they can blow inside of a sealed PVC pipe. They were given a 3' PVC pipe (0.5" diameter), a Vernier LabQuest, pressure sensor and the required stopper with single hole. The students were asked to measure the maximum pressure they could exert inside of the pipe and from this determine how much air they "blew" into the sealed pipe.
::''Required calculations; a) volume of pipe, b) mass/moles of air added from difference (or increase) in pressure upon blowing.
::''Approximate answer: ~0.1 atm increase --> ~5e-4 moles of air or ~14 mg of air.

2) Calculate the amount of work done in compressing 90 L of gas to a final volume of 70 L under a constant pressure of 2.5 bar. (show all work)

3) Book Problems on ideal gas calculations - P1.3 and P1.11

4) Adiabatic Calorimeter calculation handout/Electrical energy handout

5) Heating/Cooling Curve for Water Handout

6) LAB: Absolute Zero determination via a Pressure thermometer.

6) Graph: Temp vs. Heat Capacity of Liquid Water (based on values in Heating/Cooling Curve handout - #5 above)

7) Indicator Diagrams/Calculation of Work - 4 pages

8) Redo Ex. Prob 2.5 (q, w, H, U calcs)
