- Kelvin (K) is the SI unit of thermodynamic temperature.
- It is also referred to as the absolute temperature and hence has no degrees.
- The lowest point on the Kelvin scale is absolute zero, the theoretical state of zero thermal energy.
Only 10-3 K has been achieved
- The melting point of ice at atmospheric pressure (101325 Pa) is 273.15 K or 0oC.
Hence K = 273.15 + C
- Another defining point on the Kelvin scale is water's triple point temperature of 273.16 K (0.01oC), where at a pressure of 611 Pa (well below atmospheric pressure) water coexists in all of its phases (solid/ice, liquid/water and gas/steam/vapour) in equilibrium with each other.
