Equipment for Gas Law Experiments Water-filled manometers ere often used in volume-versus-pressure work. I have found that the plastic bottles sold with 30 oz of Redenbackx's popcorn make acellent leveling bulbs. I use the regular mouth for the manometer connection throueh a rubber stoooer and use a hot cork borer to melt a hole in the bottom to oven it for use as the too of the leveling bGh. For pressure-versus-temperature work an automotive fuel pressure~vacuumgauge mounted on a 125-mLErlenmeyer flask works well. Our students generally get an extrapolated absolute zero in the -250 to -300°C range. The gauges are inexpensive: about $15 locally and as low a s $9.49 in the J.C. Whitney catalog (Chicago, IL). We assemble the system at room temperature and take readings a t about 20' intervals over the &lo0 OC range. The rubber stopper should be tightly twisted into the mouth of the flask and the gauge damped as the pressure sometimes "pops"the gauge out of the flask near a temperature of 100 OC.
