2-Kelvin scale is adopted as the standard scale of temperature.

Answer 1

The scaling is such that there are exactly 100 degrees between the freezing and boiling points of water at standard atmospheric pressure (at sea level).

Absolute Zero, the theoretical lowest possible temperature at which all thermal vibration motion stops, is defined as 0 degrees Kelvin
