→Key Stage 5
*At [[Absolute Zero|absolute zero]], [[Molecule|molecular]] motion ceases.
*It is the baseline for the [[Kelvin]] [[temperature]] scale.
*[[Absolute zeroZero]] is equivalent to -273.15°C.*[[Absolute Zero]] represents the lower limit of the thermodynamic temperature scale.*Achieving [[Absolute Zero|absolute zero]] is impossible; it can only be approached asymptotically.*At [[Absolute Zero|absolute zero]], the entropy of a perfect crystal is exactly zero, per the third law of thermodynamics.*Near [[Absolute Zero|absolute zero]], quantum mechanical effects such as Bose-Einstein condensation can be observed.*Laboratories use techniques such as laser cooling and evaporative cooling to reach temperatures close to [[Absolute Zero|absolute zero]].
