Abstract : The vacancy mechanism of the melting process is utilized as a starting point for deriving the formula for the difference of the heat capacity of the liquid and solid metal in the neighbourhood of the melting point. From these calculations it follows that the difference Cpl - Cps is the same for all the metals and equals 3.50 J g.atom-1 K-1. This result is compared with the existing in the literature experimental data for 8 REM Y, La, Ce, Pr, Nd, Sm, Dy, Tm and the agreement is found to be very good.
