Comps 2 question:
What is the energy in eV between atoms in a typical solid state material ?
Just rough estimate ?
How is that related to the thermal energy that needs to be supplied in order to melt it ?
For example a typical bond has 1eV but we need much smaller energy to break it, why is that ?
For NaCl the latice energy is 800kJ/mol which is 7eV per atom.
Where is the mistake here ?
1eV = 6.10^18 eV, 1eV = 11000K
Thanks a lot!
