PHYWE Thermal expansion (thermal conductivity) of metals

Principle The thermal conductivity of copper and aluminum is determined in a constant temperature gradient from a calorimetrically measured heat flux. Advantages Simple setup of the temperature gradient Compact, easily transportable setup Objectives Determine the heat capacity of the calorimeter in a mixture experiment as a preliminary test. Measure the heating of water at 0 °C in the calorimeter under the influence of the ambient temperature as a function of time. First, establish a constant temperature gradient in the metal rod using two heat reservoirs (boiling water and ice water). After removing the ice pieces, measure the heating of the cold water as a function of time and determine the thermal conductivity of the metal rod.
