What information does a phase diagram give

Basically a phase diagram represents the different phases of any substance with the range of temperature and pressure in which these phases exists. It also represents the transition stages and the existsing substances in the transition stages with their phase state

A phase diagram provides a plethora of information in the form of graphs. It basically shows when a certain substance changes its form into a different stage of the matter. It has two axes and with these axes, it accurately represents the exact points where the temperature and pressure change into different states of matter. There is also a triple point where you can see a spot with all three states of matter that exist for an element and this only occurs when the temperature and the pressure are at a certain point, which differs for every element.
