U is given by U 1/4 c�nA - Afinal�M=rvfinal
Two parameters give the size of the crystal as L 1/4 Na.
Figure 7.2 Linear "crystal" represented by a chain of N atoms with a distance, the lattice constant a, leading to a crystal size L 1/4 Na.
the two substrates is explained by the diffusion of silver into the soda-lime glass substrate, this process being based on an exchange between Ag� ions in the coating and Na� ions of the substrate.
The surface area of the material is calculated from the number of gas molecules in a monolayer at the surface NS 1/4 �V S=V M�NA, where VS is the gas volume adsorbed at the surface and VM is the volume of 1 mol of gas, both under standard temperature and pressure conditions, and NA is Avogadro's number (also called Loschmidt's
