Chapter 8: Q. 8.19 (page 345)

The critical temperature of iron is $1043 K$ . Use this value to make a rough estimate of the dipole-dipole interaction energy $ε$ , in electron-volts.

Short Answer

Expert verified

The dipole interaction energy of iron = $0.011 e V$

Step by step solution

Step 1. Given information

Formula for critical temperature,

$k T_{c} = n ε$

Here,

$k$ =Boltzmann constant,

$n$ = number of nearest neighboring dipole

$ε$ = interaction energy.

Step 2. To find the dipole interaction energy of iron

We have,

$ε = \frac{k T_{c}}{n}$

Iron is BCC structure, and the value of $n$ is 8.0,

Substituting the value of $8.617 \times 10^{- 5} eV / k = k, 1043 k for critical temperature of iron T_{c} and 8.0 for n$

$ε = \frac{(8.617 \times 10^{- 5} eV / k) (1043 k)}{(8)}$

$= 0.011 eV$

The dipole interaction energy of iron = $= 0.011 eV$
