All molecular motion stop at 0 k wich is zero kelvin. At absolute 0 it stops. The temperature of 0 entropy at which all molecular motion stops equals in centigrades to - 273.15° C which is the same as 0 in kelvin degrees. Have in mind that t emperature is a measure of the average kinetic energy of the molecules in a material.
