PhysicsEnergyGCSE Created by: John ReddelCreated on: 07-04-12 14:48 Infra Red Radiation *All objects on their surfaces are contunially emmiting and absorbing IRR *An object thats hotter than it's surroundings emits more radiation than it absorbs *An object that's cooler than it's surroundings absorbs more radiation than it emits *The hotter the object the more radiation it emits 1 of 3 Kinectic Theory Solids *Strong forces of attraction *Particals are in a fixed position *Barley any energy- Vibrate around their fixed point Liquids *Weaker forces of attraction *Particals can slide over each other *More energy- can move in random directions Gases *Almost no forces of attraction *Have trhe most energy *Move about where ever they like at high speeds 2 of 3 Conduction 3 of 3
