Abstract

This study gives our calculations for thermodynamic quantities, such as the isothermal cornpressibility k(T), thermal expansivity alphap and the specific heat C-P, as a function of temperature for solid ammonia near the melting point. Our calculations, which have been performed on the basis of an experimental study given in the literature, show that those thermodynamic quantities diver e near the melting point in ammonia. This is an indication that ammonia exhibits a critical transition as one approaches the melting point in this system.
