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.
