Interpretation Introduction

Interpretation:

The triple point, temperature, and the type of solid are to be determined where solid, liquid and vapor coexist. Also, define what other triple points indicate.

Concept Introduction:

A phase has uniform physical and chemical properties and is bounded by a surface, due to which two phases can be mechanically separated from each other.

Phase diagrams are the geometrical representations of the conditions such as temperature, pressure, composition, etc. of a system at which different phases present in the system exists and are in thermodynamic equilibrium.

These phase diagrams contain phase boundaries, which are lines that mark the conditions under which multiple phases can coexist at the equilibrium. Along these lines, the transition of phase occurs.

The point where these phase boundaries intersect are the triple points. At these points, three different phases can exist simultaneously.
