i have to plan and design an experiment based on this outline: " excellent thermal conductors are also excellent electrical conductors"
could i get any ideas please?
could i get any ideas please?
Another is beryllium oxide. See http://en.wikipedia.org/wiki/Beryllium_oxidenasu said:You could show that the statement is not true, in general, by using diamond as an example : excellent thermal conductor (better than copper) and very, very poor electrical conductor (or rather very good insulator).

It's rather so-so in both respects, if you compare with a metal.256bits said:I guess salted water would fall under excellent electrical conductor but a so-so thermal conductor.
I attach a Material Safety Data Sheet for beryllium-copper (see http://www.csunitec.com/technical/MSDS/Cast%20Copper-Beryllium%202008.pdf ).marcusl said:Bob, beryllium copper is classified as a hazardous material. Not a good choice for a science project.
Look up the physics law relating the ratio of the electronic contribution to the thermal conductivity (κ) and the electrical conductivity (σ).Shordaay said:i have to plan and design an experiment based on this outline: " excellent thermal conductors are also excellent electrical conductors"

The purpose of planning an experiment to test the thermal and electrical conductivity of materials is to determine how well a given material can conduct heat and electricity. This information is important in various fields, including engineering, materials science, and physics.
The materials chosen for an experiment on thermal and electrical conductivity should be representative of the types of materials commonly used in the industry or field of study. They should also have a wide range of thermal and electrical conductivities to accurately compare and analyze the results.
The best method for measuring thermal and electrical conductivity in an experiment will depend on the specific materials being tested and the equipment available. Some common methods include using a thermocouple or a four-point probe for thermal conductivity measurements, and a voltmeter or ammeter for electrical conductivity measurements.
To obtain accurate and reliable results, it is important to control variables in an experiment on thermal and electrical conductivity. This can be done by keeping the experimental conditions, such as temperature and humidity, consistent throughout the experiment. It is also important to use the same measuring equipment and techniques for each material being tested.
There are several potential sources of error in an experiment on thermal and electrical conductivity, including variations in the materials themselves, inaccuracies in measurement equipment, and human error. It is important to carefully design the experiment and conduct multiple trials to minimize these sources of error and obtain reliable results.
