i.1. States of Matter in Our Tiny Particle Universe

Matter, the fundamental substance composing the universe, is the cornerstone of our understanding of the physical world. Everything in the universe that is composed of both mass and volume, meaning they occupy space and have weight is called matter. The matter is made up of very tiny particles and these particles are so small that we cannot see them with naked eyes.

Particle Nature of Matter: Particle Nature with Dettol Drops

  • Made of Millions of Particles: The particles of the matter are really small as there are millions of tiny particles in just one crystal, any particle, which keep on dividing themselves into smaller and smaller particles. 
    • Example: This can be visually seen when a drop of dettol is added to water.

Characteristics of Particles of Matter: Space, Motion, and State of Matter

  • Space Between Particles: The particles of one type of matter get into the spaces between particles of the other, proving that there is enough space between particles of matter. 
    • Example: When we make tea, coffee or lemonade (Nimbu Paani ), particles of one type of matter get into the spaces between particles of the other.
  • Constant Motion of Particles: Particles of the matter are in constant motion and this movement is due to the kinetic energy they possess, which depends on the temperature. 
  • Attractive Force: Particles of matter have force acting between them, which keeps them together. 
    • The strength of this force of attraction varies from one kind of matter to another.

School of thought

Two schools of thought emerged regarding the nature of matter, one school believed matter to be continuous like a block of wood (continuous) and the other believed that matter to be made up of particles like sand (particulate).
