: [[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:

*[[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.

*[[Thermal Radiation]] - Objects can [[emit]] and [[Absorb (Physics)|absorb]] [[Thermal Radiation]]. The higher the [[temperature]] the more [[Thermal Radiation]] they [[emit]].
