Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as .
The Kelvin scale is an absolute, thermodynamic temperature scale using absolute zero as its null point, the temperature at which all thermal motion ceases in the classical description of thermodynamics.
Temperature of absolute zero cannot be physically achieved because it's impossible for the entropy (or disorder) of a system to hit zero.
