Conduction 3F: Temperatures inside walls

In this model, three layers (labeled as "A", "B", and "C") that have different thermal conductivities fill the space between the heater and an object. Your challenge is to find out which layer has the greatest thermal conductivity and which has the lowest by running a sequence of tests for different layer configurations.

1. Run the model and note the temperatures measured by the four thermometers.
2. Turn the graph on to watch the changes of the temperatures.
3. Use the buttons at the upper-right corner of the graph window to rescale the curves if necessary.
4. Change the order of the layers using the drop-down menu to test a different setup.
5. Repeat the above steps until you reach the conclusion.

After you have completed your investigation, answer the questions in your workbook.
