Understanding Phases of Matter: Properties and Processes

In this lesson, we explore the different phases of matter: solid, liquid, and gas. Learn to identify physical and chemical properties such as burning, melting, rusting, and photosynthesis. Additionally, distinguish between extensive and intensive properties, with examples including melting point, volume, and density. Engage in quiz activities to solidify your understanding of these concepts and recognize how matter behaves in various states.

  5. Phases of Matter • The Solid Phase of Matter • Matter in the solid phase has a definite shape and a definite volume. • In the solid phase, the particles of matter are packed together in relatively tight, fixed positions.

  6. Phases of Matter • The Liquid Phase of Matter • Matter in the liquid phase has a definite volume but no definite shape. • In the liquid phase, the particles are close together but can move around one another.

  7. Phases of Matter • The Gas Phase of Matter • Matter in the gas phase has neither a definite shape nor a definite volume. • Gas particles move very rapidly and are at a much greater distance from one another as compared to solids and liquids.
