Question

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

Answer 1

273 kelvin,0 degree celcius,32 degree fahrenheit option is the correct answer

Answer 2

Answer:

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:

$\frac{Tc}{5} = \frac{Tfr-32}{9} =\frac{Tk-273}{5}$

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
