Hello! I am supposed to explain the behaviour of the thermal conductivity of tungsten. I have plotted the relation
http://img340.imageshack.us/img340/9776/heatcond.jpg [Broken] is also experimental data
Temp[0 10 50 100 300 500 1000 2000 3400]
and thermal conductivity coefficient
[tex]\lambda[/tex] 0 97,1 4,28 2,08 1,74 1,46 1,18 1 0,9]
Can someone explain the mechanism to me? Why does the thermal conductivity reache its maximum for T=10K ? and after that it gradually decreases and after some temp is behaves almost like constant?
How this can be explained?
