If an object is warmer than its surroundings, it will radiate Infrared Radiation. |
If an object is cooler than its surroundings, it will absorb Infrared Radiation. |

|
Dark, matt surfaces are good emitter and absorbers of Infrared Radiation. |
Light, shiny surfaces are poor emitters and absorbers of Infrared Radiation. |

Kinetic Theory explains the properties of the states of matter. |
Solids - fixed shape, fixed volume. Liquids - no fixed shape, fixed volume. Gases - no fixed shape, no fixed volume. |

Thermal Conduction
- heat energy is transferred through solid materials by conduction. - particles in a solid are always moving. - the hotter the particles, the more energy they have to vibrate. |
Conduction in Metals
- metals have lots of free electrons which gain more energy from collision during heating. - the energy is transferred faster. - the electrons transfer energy more quickly as they travel through the metal. |
