Kelvin temperature

What's the kelvin temperature scale and how does it work?

[Joshua_R]

The Kelvin scale is the SI unit of thermodynamic temperature.
It was named after William Thomson, first Baron Kelvin, who was born in 1824 and died in 1907.
His work on the conservation of energy led to the second law of thermodynamics - it is impossible for an unaided self-acting machine to convey heat from one body to another at a higher temperature.
The Kelvin scale starts at absolute zero ( -273 degrees Celsius ). This is the theoretical lowest possible temperature. All substances would be solids at this temperature.
The Kelvin scale increases in the same way as the Celsius scale, but is 273 degrees higher : 0 degrees Celcius = 273 K, 100 degrees Celsius = 373 K.
