# Thermal conduction coefficient of metals

Product No: P1043200

Principle

One end of a U-shaped metal rod is immersed in boiling water and the other in cold water. From the warming of the cold water qualitative and quantitative statements can be made about the influence of the rod's composition, length and diameter on the heat flow through it. Since the performance of the experiment is time consuming, the individual measurements should be carried out by different groups of students: a least 4 teams should be formed. Each team performs the experiment with only one rod; for the evaluation the results of all the groups are pooled.

Investigate the conduction of heat in metals as a function of the material and the dimensions of the rod.
To do so lay a metal rod between two beakers - one with hot and the other with cold water, then measure the temperature changes in the hot water.
