==Key Stage 5==
===Meaning===
[[Absolute zero]] is the theoretical [[temperature]] at which a [[system]] reaches its minimum possible [[energy]], corresponding to 0 [[Kelvin|K]].
===About Absolute Zero===
*At [[absolute zero]], [[Molecule|molecular]] motion ceases.
*It is the baseline for the [[Kelvin]] [[temperature]] scale.
*[[Absolute zero]] is equivalent to -273.15°C.
===Examples===
*The coldest recorded [[temperature]] in a laboratory setting is a fraction of a [[kelvin]] above [[absolute zero]].
*Space probes use devices cooled to near [[absolute zero]] to detect faint [[infrared]] signals.
