Demo Title: Heat Transfer - Heat Pipe or Aluminum Bar
Condition: Excellent
Principle: Conductivity
Area of Study: Thermodynamics
Equipment:
Heat Transfer Apparatus with Aluminum Bars, Digital Thermometers (2), Interface with Two Thermometer Probes, Heat Pipes, Styrofoam Containers.
Procedure:
Put very hot to boiling water into one of the Styrofoam containers, and cold or ice water into the other. Make sure there is only water and no ice in the cold water reservoir. Place the heat pipes in the orientation indicated on the reservoirs and cover with the lid that has the thermometers inserted. Once the thermometers have come to a steady reading, you may start the data collection. The temperature readings should converge as the heat pipes transfer the heat from the hot to the cold reservoirs.
Put cold water in one cup and hot water in the other. Monitor the temperature over a period of time to plot heat transfer from one cup to the other.
