Answer :

If a solution has a temperature of 255 k, then its temperature in degrees Celsius is - 18 °C

The temperature is defined as ,

Temperature is the degree of hotness or coldness of a body, measured in degrees Fahrenheit or degrees Celsius.

Calculation ,

The temperature is converted from degree Celsius to kelvin as ,

Let suppose temperature = X °C

Then temperature in kelvin =  X °C  + 273 =  ( X  + 273 ) K

If a solution has a temperature = 255 K

Temperature in degrees Celsius =  255 K - 273 = - 18 °C
