Description

In a galvanic element that consists of identical half cells with different temperatures, a potential difference can be measured. The system aims to even the temperature differences which leads to solution and precipitation of copper in the half cells.

In experiment C4.4.3.5, a galvanic element is set-up that consists of identical half cells with different temperatures. The potential difference is measured over time.
