Kinetic particle theory

• The three states of matter

  the three states of matter is solid liquid and gas
• Solid arrangement


  The arrangement of particles in a solid is packed really closely in a regular manner
• Solid particles movement

  The particles in a solid vibrate in a fixed position
• Solid particles kinetic energy

  The particles in solid has very less kinetic energy
• Forces of attraction in solid particles

  Particles in solid have a strong forces of attraction
• The arrangement of liquid

  The particles are packed closely to one another in a disorderly manner.
• The movement of particles in liquid

  The particles slide over one another
• Kinetic energy in liquid

  The kinetic energy in particles in liquid is slightly more
• forces of attraction of liquid

  The particles in liquid has a strong forces of attraction
• Arrangement of particles in gas

  The particles are far apart one another.
• Movement of particles in gas

  The particles move around in a rapidly in a random motion
• Kinetic energy in particles in gas

  There is alot kinetic energy in the particles in gas
• Forces of attraction in particles in gas

  Particles in gas has a very weak forces of attraction
• Melting


  Melting is when solid turns into liquid. The particles gain kinetic energy and vibrates faster as the temperature increase. once it reaches the melting point, the temperature remains the same till all the solid is melted into liquid as suffi heat energy is taken in to overcome storng forces of attraction between particles, so the particles mover further apart and away from fixed position.
• Boiling

  Boiling is when liquid turns into gas. The particles gain kinetic energy and move faster as the temperature increases. onces the temperature reaches the boiling point, the temperature remains constant till all the liquid is boiled into gas as enough heat energy is taken in to overcome strong forces of attraction between the particles so the particles mover further apart and move rapidly and freely in random direction.
• Freezing


  Freezing is when liquid is turned into solid. The particles loses kinetic energy and moves slower as the temperature decreases. once the temperature reaches the freezing point, temperature remains constant till all the liquid turns into solid as heat energy is released as the particles are attracted to each other to form a solid. Heat energy is given out to the surrounding
• Condensation


  Condensation is when gas turns into liquid.

  particles lose kinetic energy and moves slower as the temperature decreases. when it is cooled to the boiling point, temp remains constant as heat energy is given out and move closer to each other in a random motion.
• How to know if the substance is pure or impure

  Pure substances has a fixed melting and boiling point
