WL 374

Heat Conduction in Solids

Technical Description

The fundamental laws of steady-state thermal conduction in solid bodies can be investigated with this benchtop unit. The specimens are arranged between an electrical heater and a water-cooled plate. A Dewar vessel prevents the exchange of heat with the surrounding environment. The specimens are equipped with several temperature measuring points. The heat transfer rate is determined via the current and voltage of the heater.
A supply of cooling water is required.

Learning Objectives / Experiments

- Determination of the thermal conductivity of various
specimens
- Temperature curves as a function of length
- Heat transfer through different specimens
connected in series

Features

* Compact design₁
