Given :
Two samples of matter differ in temperature by 20°C.
To Find :
The difference in temperature of these two samples using the Kelvin scale.
Solution :
Let , initial and final temperature is [tex]T_i[/tex] and [tex]T_f[/tex] .
So , [tex]T_f-T_i=20^oC[/tex] .
Now , temperature in kelvin is given by [tex](T_i+273)[/tex] and [tex](T_f+273)[/tex] .
So , difference between them is :
[tex]=(T_f+273)-(T_i+273)\\\\=T_f-T_i\\\\=20\ K[/tex]
The difference in temperature of these two samples using the Kelvin scale is 20 K .
Therefore , the magnitude of difference in kelvin and Celsius is same .
Hence , this is the required solution .
