Expansion || Heat is a form of energy, from the vibrations of particles inside matter. Temperature is a consequence of heat energy Temperature scales are based on 'fixed points' The fixed points that define the celsius temperature scale rely on the melting of ice and boiling of water (at normal atmospheric pressure) 0K is absolute zero; it is measured on the kelvin scale Temperature in K + 273 = temperature in ' C The fahrenheit scale is the only other commonly used scale; it is not part of SI. When heated, most materials expand. The amount of expansion depends on the material, the original dimensions and the temperature change Water is an exceptional case: it has its maximum density at 4 ' C. Therefore ice floats. ||

Heat movement Solids: conduction - insulators and good conductors - mechanisms of particle vibration or movement. Types of materials. Applications of good and poor conductors Liquids and gases: convection. Change of density resulting in rising 'fluid cells' eg hot air balloons Vacuum and transparent substances: radiation: Infra-red - reminder of electromagnetic spectrum Keeping warm, or keeping cool -examples from everyday life and nature. || Ilmiö p.105-112.
