Kinetic theory and conduction
Kintetic theory is how particles move in solids, liquids and gases.Three states of matter; Solids: Strong and close together in fixed regular arrangement, dont have much energy so they vibrate in fixed postions.Liquids: weaker forces of attraction, close together, can move past each other to make irregular arrangements. more energy, random directions at low speeds.Gases: Almost no forces of attraction. alot of energy, free to move, random directions at high speeds.when you heat a substance they have more kinetic energy.
Conduction: CONDUCTION OF HEAT ENERGY is the process where VIBRATING PARTICLES pass on their EXTRA KINETIC ENERGY to NEIGHBOURING PARTICLES
usually conduction is faster in dender solids, closer togther, so they collide more often. materials that have larger spaces between them conduct heat more slowly they're called insulators.
metal conduct well because of free electrons, they're free to move and pass on thier extra kinetic energy, this is a faster way of transferring energy than slowly passing it through neighbouring atoms.
