Answer:
273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
Step-by-step explanation:
The most usual temperature scales are Kelvin, Celsius and Fahrenheit, and they are related by the equation:

Where Tc is the temperature in degress Celsius, Tfr, the temperature in degrees Fahrenheit, and Tk the temperature in Kelvin. So, for Tc = 0ºC:
0/5 = (Tfr-32)/9
Tfr - 32 = 0
Tfr = 32ºF
0/5 = (Tk-273)/5
Tk - 273 = 0
Tk = 273K
