Fraction of the vacant atom
The fraction of the atom that are vacant for the copper atom at its melting temperature is determined using the equation below;
[tex]\frac{N_v}{N} = e^{(\frac{-Q_v}{KT} )[/tex]
where;
- Qv is the vacancy formation of the copper = 0.9 eV/atom
- K is Boltzmann constant = 8.62 x 10⁻⁵ eV/atom.K
- T is the temperature = 1357 K
The fraction of the atom that are vacant for the copper atom at its melting temperature is calculated as follows;
[tex]\frac{N_v}{N} = e^{(\frac{-0.9}{8.62 \times 10^{-5} \times 1357} )}\\\\\frac{N_v}{N} = 4.57\times 10^{-4}[/tex]
