Abstract

This experiment is a study of the 3 omega method, done by suspending a wire in a sample to measure the thermal conductivity. We also tested various gauges and metal types of wire to see how these affect measurements. Two gauges of copper wire (40 and 28) and one gauge of tungsten wire (38) were used to measure the thermal conductivity of paraffin wax. These individual measurements are compared to the actual measurement of 0.25 W/mK. This experiment was a continuation of previous work and a few changes were made, resulting in slightly more concrete results.
