100 0 -273 Boiling point of water Freezing point of water Absolute zero 373 273 0 Temperature differences are the same on the Celsius and Kelvin scales. The temperature difference between the freezing point and boiling point of water is 100C or 100 K. In Kelvin scale, zero is the point at which the kinetic energy of the atoms is O J. the kinetic energy of the atoms is 373 J the kinetic energy of the atoms is 100 J the kinetic energy of the atoms is 273 J
