States of Matter and Their Processes

The video introduces the concept of matter, highlighting its properties of mass and volume. It explains the three states of matter: solid, liquid, and gas, each with distinct characteristics. The video further explores how matter transitions between these states through processes like melting, solidification, evaporation, and condensation.
