Thermal Conductivity of a Poor Conductor – Lee’s Method
-
Check the continuity of the liquid column and the linear behavior of the thermometers before
beginning the experiment.
-
This experiment involve generation of steam and handling of the steam bath during the experiment
during steps # 5,6 of procedure. Hence, use the gloves without fail while following the steps #
5,6.
-
Keep the steam outlet away from electrical connections
Setup the apparatus in a way to ensure that while following the step # 5,6of procedure the
thermometers are not removed or damaged.
-
There will be radiation loss due to thickness. But, we consider only loss due to surface. Hence,
we should consider specimen so, that thickness is negligible to that of diameter.
-
The graph gives curve, hence while calculating slope proper care should be taken.
