P1.1.2 Kinetic theory

P1.1.2 Kinetic theory

1. explains the different states of matter

   • by describing how particles move in soilds, liquids and gases
     • solid
       • strong forces of attraction, fixed rigid- no much energy- so can only vibrate
     • liquid
       • weaker bonds- close but can move to form irregular patterns- more energy than solid- move random directions at low speeds
     • gas
       • v. little forces of attraction, more energy- free to move in random directions and at high sppeds

2. The particles of a gas have more energy than that of a liquid, which have more energy than particles in a soild
