What are the Kelvin and Celsius temperature scales?

Answer 1

The Celsius scale sets the freezing point of water as zero degrees and the boiling point of water as 100 degrees (hence its alternative name of the centigrade scale). The Kelvin scale sets as zero the temperature at which an ideal gas would have a volume of zero, and all thermal motion ceases, so it is sometimes called absolute zero. The other fixed point is then the triple point of water, which is set at 273.16 K. The divisions of the two scales have the same magnitude.

Answer 2

The Kelvin temperature scale is an absolute temperature scale where 0 Kelvin represents absolute zero, the theoretical point of zero thermal energy. The Celsius temperature scale is based on the properties of water, with 0 degrees Celsius representing the freezing point and 100 degrees Celsius representing the boiling point of water at standard atmospheric pressure.
