Why is it not required to add 273 in the temperature given in degree celsius to convert it into kelvin in case of equations of elevation in boiling point and depression in freezing point? Share with your friends Share 2 Vartika Jain answered this Dear Student, ∆Tf is the change in temperature. The difference in temperature will remain same irrespective of the units. Even if you add 273, still the answer will be same∆Tf= T1-T2Suppose T1 and T2 are in °CSo, ∆Tf= (T1+273)-(T2+273) =T1+273-T2+273 =T1-T2 4 View Full Answer Anshul Rana answered this because the difference will remain the same. suppose if T1=10 degree and T2=20 degree the difference comes out to be 10 and if you take these quantities in kelvin i.e. T1=283K and T2=293K the difference is 10 which is same as above 2
