How can convection be reduced?
This model has two compartments with a warm surface at the bottom.
In the middle of the right-hand compartment there is a barrier.
Your task is to compare the rates of the convective heat transfer from the bottom
to the top in the two compartments.
- Run the model and note the temperatures measured by the two thermometers.
- Turn the graph on to watch the changes of the temperatures.
- Use the buttons at the upper-right corner of the graph window to rescale the curves if necessary.
Click on a thermometer to highlight its data.
- When the model stops, write the temperatures measured by the thermometers and the temperature at the bottom heater
in your workbook.
- Try changing the location of the barrier or adding more barriers. Click on the barrier to change size, move, or copy it.
- Try to connect what you observe in this model to the attic in a house.
