Abstract:

This is a simple apparatus which illustrates the dynamics of heat flow in a rod. It consists of a heater and two thermistors embedded in a copper (or other metal) rod. Together with associated electronics, the experiment is controlled by one output and three inputs of a computerized data acquisition system.  Further investigation of the system is accomplished by placing the apparatus in a vacuum.
