Description
Summary:	Shows the measurement of the thermal conductivity of argon over a wide range of vacuum pressures. Students record the time it takes for the temperature of a water bath to drop exactly 2 degrees Celsius while surrounded by a double-walled flask filled with argon at various pressures. By plotting the reciprocal of the cooling time as a function of gas pressure, one can verify the regions of constancy of thermal conductivity predicted by kinetic theory.
