==Key Stage 3==
===Meaning===
'''Heating''' is a way of [[Energy Transfer|transferring energy]] from one [[Energy Store]] into another through [[Conduction]], [[Convection]] or [[Thermal Radiation]].
===About Heating===
: [[Heating]] happens when two [[object]]s of different [[temperature]] are in contact with one another.
: Energy is transferred from the hotter to the cooler object until they reach '[[Thermal Equilibrium]]' which means they are both at the same [[temperature]].
: [[Heating]] [[Energy Transfer|transfers energy]] from the [[Thermal Energy Store]] of one [[object]] to the [[Thermal Energy Store]] of another [[object]].
There are three ways that [[heating]] can occur:
*Conduction - [[Vibrate|Vibrating]] [[particle]]s [[collide]] with other [[particle]]s passing on their [[energy]].
*Convection - [[Fluid]] at high [[temperature]] is less [[Density|dense]] than [[fluid]] at low [[temperature]] so the high [[temperature]] [[fluid]] rises and the low [[temperature]] [[fluid]] sinks.
*Radiation - Objects can [[emit]] and [[Absorb (Physics)|absorb]] [[Thermal Radiation]]. The higher the [[temperature]] the more [[Thermal Radiation]] they [[emit]].
