Answer :

All the three given represent the same temperature in different scales

Kelvin is absolute temperature where 273 is added to the centigrade value

K = C+273

HEnce 273 Kelvin when converted into centigrade gives

273-273 = 0 degree centigrade

273 K = 0 C

-----------------------------

Fahrenheit to centigrade conversion is

C=[tex]\frac{5}{9} (F-32)[/tex]

Hence when F=32, we get C=0

Thus all three are one and the same.
