==Key Stage 4==
===Meaning===
'''Temperature constancy''' occurs when the [[Thermal Energy Store|thermal energy]] [[emit]]ted by an [[object]] is equal to the [[Thermal Energy Store|thermal energy]] [[Absorb (Physics)|absorbed]] by that [[object]].

===About Temperature Constancy===
: Any [[object]] with a [[temperature]] above [[Absolute Zero|absolute zero]] [[emit]]s [[Black Body Radiation|black body radiation]]. As the [[temperature]] increases the [[energy]] [[emit]]ted increases.
: [[Object]]s will [[Absorb (Physics)|absorb]] [[radiation]] that [[Incident Ray|incidents]] its surface. The [[colour]] and [[reflectivity]] of the [[object]] determine the amount of [[radiation]] [[Absorb (Physics)|absorbed]].
: When the rate of [[energy]] [[emission]] and the rate of [[energy]] [[Absorb (Physics)|absorption]] are equal the [[object]] will remain at a '''constant temperature'''.
: If the rate of [[emission]] is greater than the rate of [[Absorb (Physics)|absorption]] then the [[object]] will decrease in [[temperature]] until the rates are equal.
: If the rate of [[emission]] is less than the rate of [[Absorb (Physics)|absorption]] then the [[object]] will increase in [[temperature]] until the rates are equal.
