What are the three states of matter?

The three main states of matter are solid, liquid, and gas. They differ in the arrangement and movement of their particles, as well as in their properties.


1. Solid

  • Particles: Tightly packed, arranged in fixed positions.
  • Shape & Volume: Definite shape and definite volume.
  • Movement: Particles vibrate in place but do not move freely.
  • Properties: Rigid, hard, and incompressible.
  • Examples: Ice, wood, iron, stone.

2. Liquid

  • Particles: Close together but not in fixed positions.
  • Shape & Volume: Definite volume but no fixed shape (takes the shape of the container).
  • Movement: Particles slide past each other, allowing flow.
  • Properties: Fluid, not easily compressible.
  • Examples: Water, oil, milk, juice.

3. Gas

  • Particles: Far apart, move freely and rapidly.
  • Shape & Volume: Neither definite shape nor definite volume (expand to fill container).
  • Movement: Random and high-speed motion.
  • Properties: Easily compressible, low density.
  • Examples: Oxygen, carbon dioxide, air, hydrogen.

Summary:

  • Solid → fixed shape & volume.
  • Liquid → fixed volume but variable shape.
  • Gas → no fixed shape or volume.
