Grade 12 Physics Unit 1 Part 2/Phase Diagram

Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs. In addition, two states of the substance coexist in equilibrium on the lines or curves. A phase transition is the transition from one state of matter to another. There are three states of matter: liquid, solid, and gas. #Grade_12_Physics #For_Ethiopian_students #Phase_diagram
