kinetic theory describes how particles move in solids, liquids and gases. | The energy an object has because of its movement is called kinetic energy. |

|
solids strong forces of attraction hold particles in fixed regular arrangement |

|
Liquids weaker forces of attraction close together but move past each other, irregular arrangements. more energy than solids so move in random directions at low speeds |

|
gases almost no forces of attraction, have more energy so are free to move in random directions and high speeds |

when you heat a substance you give the particles more kinetic energy KE therefore vibrate and move faster causing melting and boiling |
CONDUCTION OF HEAT IS THE PROCESS WHERE VIBRATING PARTICLES PASS ON THEIR EXTRA KINETIC ENERGY TO NEIGHBORING PARTICLES. | |
This process continues throughout the solid and some of the KE is passed all the way through causing a rise in temperature at the other side. | |
