Does anyone know of any materials whereby the thermal conductivity can be changed by passing an electrical current through the material?
Homework Answers
Materials that become superconductors have different thermal conductivities in the normal and the superconducting state. When in the superconducting state, starting a current larger than the critical one will drive such a material to its normal state, thereby altering its thermal conductivity.

can you write a conclusion for the report? Thermal Conductivity Lab Introduction The objective of this lab is to explore the thermal conductivity of various materials using Fourier’s Law and a steady state system. Certain materials are more effective heat conductors than others. The effectiveness of a given material at heat conduction is influenced by many factors, including density, molecular structure, and chemical composition. Fourier’s Law takes these factors into account to calculate Q, or the joules per second rate...

The core is at 37C , skin-fat layer thermal conductivity k_s =
0.3 W/m-K, skin emissivity E_s = 0.95, skin-fat thickness l_s = 3
mm, and convection coefficient ℎ_air = 2 W/m2 -K. The jacket has
thermal conductivity of k_j = 0.5 W/m-K, jacket emissivity E_j =
0.02, and jacket thickness l_j = 2 cm.
a) Write two energy balances, one at the skin-jacket interface
and another at the jacket-air interface. Can any of the terms in
your energy balances...
Why as the temperature increases does the electrical conductivity decrease in metals but increase in electrolytes?...
Why as the temperature increases does the electrical conductivity decrease in metals but increase in electrolytes? Why do two circular current loops of the same size and with the same current direction attract each other when one is placed on top of the other but repel each other when they are placed side by side on the same plane? What happens in these two situations if the directions of current are opposite in the two loops? What are the similarities...

Does anyone can explain to me when income tax applied is there any effect on calculating the break even point and saftey margin? I guess theres no effect but why? Is it because at break even point no tax is paid or income tax does not take effect on fixed costs?

Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the thickness d. Q kA (T2-T)...
