We are asked to identify which will have a lower temperature: the triple point or the normal melting point, considering that the solid phase is denser than the liquid phase.
We are given the information that the triple point exists at a pressure below 1 atm.
The density of a substance is greater in its solid phase than in its liquid phase.
If the triple point in the phase diagram of the substance is below 1.0 atm, then which will necessarily be at a lower temperature, the triple point or the normal melting point?
