Answer:
Given, triple point of water on scale A = 200 A
Triple point of water on scale B =
350 B.
As per question, 200 A = 350 B=
273\[{{\text{l}}_{\text{1}}}\text{=l;}{{\text{A}}_{\text{1}}}\text{=m}{{\text{m}}^{\text{2}}}\text{;}\]16
K
or \[{{\text{Y}}_{\text{1}}}\text{=2
}\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{11}}}\text{N}{{\text{m}}^{\text{-2}}}\]
and \[\text{B,}{{\text{l}}_{\text{2}}}\text{=l;}{{\text{A}}_{\text{2}}}\text{=m}{{\text{m}}^{\text{2}}}\text{;}\]
If
\[\frac{{{T}_{F}}'-32}{180}=\frac{{{T}_{K}}'-273\cdot 15}{100}\]represent the
triple point of water on two scales A and B, then
\[\frac{{{T}_{F}}'-{{T}_{F}}}{180}=\frac{{{T}_{K}}'-{{T}_{K}}}{100}\]
or \[{{T}_{F}}'-{{T}_{F}}=\frac{180}{100}\left( {{T}_{K}}'-{{T}_{K}} \right)\]
or \[{{T}_{K}}'-{{T}_{K}}=1K,\]
