• question_answer 25) Triple point of water is A) ${{273.16}^{o}}F$B) $273.16\,K$C) $273.16{{\,}^{o}}C$D) $273.16\,R$

Triple point of water is 273.16 K. $\frac{{{P}_{1}}}{{{P}_{2}}}{{\left( \frac{{{T}_{1}}}{{{T}_{2}}} \right)}^{4}}=\left( \frac{273-73}{273+327} \right)={{\left( \frac{200}{600} \right)}^{4}}=\frac{1}{81}$
