Answer 2

Answer : The correct option is, (D) 273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit

Explanation :

Conversion of degree Celsius to Kelvin :

`K=^oC+273`

Conversion of degree Celsius to degrees Fahrenheit :

`^oF=((9)/(5)* ^oC)+32`

By using these two conversion factors, we get the three temperature readings all mean the same thing.

For option A :

`K=^oC+273=100+273=373K`

`^oF=((9)/(5)* ^oC)+32=((9)/(5)* 100)+32=212^oF`

For option B :

`K=^oC+273=100+273=373K`

`^oF=((9)/(5)* ^oC)+32=((9)/(5)* 100)+32=212^oF`

For option C :

`K=^oC+273=0+273=273K`

`^oF=((9)/(5)* ^oC)+32=((9)/(5)* 0)+32=32^oF`

For option D :

`K=^oC+273=0+273=273K`

`^oF=((9)/(5)* ^oC)+32=((9)/(5)* 0)+32=32^oF`

From the given options, only option (D) is correct.

Hence, the correct option is, (D) 273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
