Explanation
to conver from Fahrenheit to kelvin, we can use this formula.
[tex]\mleft(F-32\mright)\times\frac{5}{9}+273.15=k[/tex]then
Let
[tex]\begin{gathered} F=84 \\ \end{gathered}[/tex]now, replace.
[tex]\begin{gathered} (F-32)\times\frac{5}{9}+273.15=k \\ \text{ }(84-32)\times\frac{5}{9}+273.15=k \\ \text{ }(52)\times\frac{5}{9}+273.15=k \\ 302.038=K \end{gathered}[/tex]therefore, the answer is 302.038 °K
