Important Physical Properties of matter

  • Matter is made up of particles
  • The particles are very small in size
  • These particles have spaces between them
  • These particles are constantly moving
  • Particles attract each other
  • There are 3 states of Matter-Solids, Liquids and Gases
  • Matters can change state from one form to another

 


Matter is made up of Particles


As per Old School of thought

  • Matter is Made up of continuous particles
    Example like a block of wood

As per New school of thought

  • Matter is made up of small particles like sand

 

Activity to Show Matter is Made up of Particles

 

  • Take a beaker
  • Fill it half with water
  • Put some salt in it
  • Stir it with help of glass rod
  • After some time, we observe particles of salt disappear

 

Reason

This is because

When we dissolve salt in water, the particles of salt get into the spaces between particles of water

 

Lets look at the Characteristics of Particles of Matter
