Question

The absolute temperature (Kelvin scale) T is related to the temperature tc on the Celsius scale by tc = T - 273.15. Why do we have 273.15 in this relation and not 273.16?

Answer 1

The temperature 273.16 K is the triple point of water. The temperature 273.15 K which is the melting point of ice in Kelvin scale corresponds to 0°C in Celsius scale.
so, The absolute temperature (Kelvin scale) T is related to the temperature $T_C$ on the Celsius scale by $T_C$ = T - 273.15.

Hence, the relation has 273.15 in it and not 273.16

Answer 2

Answer:

tc = T - 273.15

Explanation:

The triple point of water temperature is =273.16

It is not the melting point of ice.

The melting point of ice on Celsius scale temperature is = 0° C

Its crossponding value on Kelvin scale = 273.15

Hence,

absolute temperature T ( Kelvin scale ), is related to temperature tc , on celcius scale as ,

tc = T - 273.15
