About 200 years ago , It was noticed that sample of gas that is cooled decreases in volume in a regular way. If the volume were to continue to decrease in the same way it would become zero at about -273.15 degree Centigrade. This temperature is the minimum temperature, the absolute zero. The new temperature scale as devised by Lord Kelvin which is known as Kelvin scale. it is defined in such a way so as to permit law of Thermodynamics.
The absolute zero is taken to be 0 K(degree kelvin) and the triple point of water is taken as 273.16K. Triple point of water is the pure liquid water , ice , and water vapor in equilibrium.Thus boiling point of water at one atmosphere is 373.15K and freezing point of water at one atmosphere is 273.16K.
Below is the formula defining the relationship of Kelvin temperature a well as Celcius as below:
K = C + 273.16
K - > Kelvin temperature
C -> Celsius temperature
