  • Data Collection System
  • Absolute Pressure Sensor with Quick Release, Connectors, and Plastic Tubing
  • Stainless Steel Temperature Sensor
  • Stand, with Clamp
  • Hot Plate
  • Graduated Cylinder, 25-mL
  • Graduated Cylinder, 250-mL
  • Erlenmeyer Flask, 250-mL
  • Beaker, 1500-mL
  • 100% Ethanol, 50 mL
  • Acetone, 50 mL
  • Electrical Tape
  • Mesh Pad, with Asbestos
  • Water, 1200 mL



    • Gathered all equipment and materials. Inspected all equipment for damage or contamination.
    • Set up Data Collection System, assembled GLX, pressure sensor, associated tubing, with stopper, and temperature sensor.
    • Measured the volume of the Erlenmeyer flask, by filling it with water, then pouring the contents into the graduated cylinder. Dried flask.
    • Wrapped the Erlenmeyer flask with the electrical tape.
    • Covered with Stopper and associated tubing, then measured base atmospheric pressure.
    • Filled 1500-mL beaker with 1125 mL of water, and placed beneath stand. Placed temperature sensor in water bath.
    • Mounted the Erlenmeyer flask on the stand, ensuring that as much of it is immersed as possible within the bath.
    • Turned on Hot Plate, and waited until the water bath reached a temperature of 80ºC.
    • Measured 50.0 mL of Ethanol, and placed it in the Erlenmeyer flask.
    • Waited for the Ethanol to boil, and the Ethanol gas to fill the flask.
    • Removed flask from water bath, sealed flask, and placed on mesh pad.
    • Measured the shift in pressure as the temperature decreased, stopped measurements once the temperature reached 30ºC, then repeated the process with Acetone in place of Ethanol, and a water bath of 60ºC.
    • Disposed of solutions in designated containers. Cleaned all glassware, set them to dry in their designated areas, and returned all equipment to its point of origin.
