Phase Diagrams and Solidification 1
Latest content Dhaka University of Engineering & Technology, Gazi
A phase diagram is a graphical representation that shows the phases of a substance as a function of temperature and pressure. It illustrates the conditions under which distinct phases (solid, liquid, gas) exist and coexist. 
 
In a typical phase diagram, you will find: 
 
1. Axes: The x-axis usually represents temperature, while the y-axis represents pressure. 
 
2. Phase Regions: Different areas on the diagram indicate different phases: 
 - The solid phase is typically found at low tempera...
