Particles of matter are attracted to each other by varying strengths.

Let us consider 2 different scenarios;

 

Scenario 1

  • Take a coin, rubber band and chalk.
  • On trying to hammer the chalk and coin, the chalk gets powdered with great ease. On the other hand the coin does not break easily.
  • The rubber band, if pulled with some effort, breaks.
  • This shows that the coin has relatively strong force of attraction followed by rubber band and chalk has the least force of attraction.

Scenario 2

  • If we try to move our hand through water and air, our hands can move easily through air as against the water.
  • This is because the force of attraction between the particles in water is greater than that in air.

We can also conclude that solid has the greatest amount of force of attraction between particles, followed by liquids and gases have the least amount of force of attraction.
