Study Notes
State Changes Diagram
- The state changes of a substance can be visually represented using a diagram
- The x-axis of the diagram represents time, and the y-axis represents temperature.
- The states of matter are represented as follows:
- Solid: The substance is in a solid state at point a.
- Liquid: The substance is in a liquid state between point b and point c.
- Gas: The substance is in a gaseous state at point c.
- Melting Point: Point b represents the melting point, where the solid and liquid states coexist.
- Boiling Point: Point c represents the boiling point, where the liquid and gas states coexist.
