Which three temperature readings all mean the same thing?
273 kelvin, 0 degrees celsius, 32 degrees fahrenheit
100 kelvin, 0 degrees celsius, 32 degrees fahrenheit
273 kelvin, 100 degrees celsius, 212 degrees fahrenheit
373 kelvin, 100 degrees celsius, 273 degrees fahrenheit

273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit

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

i'm wiling to try and you : )
