Question

Um termômetro mede uma temperatura igual a 10 ºF, determine o valor dessa temperatura na escala Celsius e Kelvin.

Answer 1

$\boxed{\dfrac{T_C}{5}=\dfrac{T_F-32}{9}=\dfrac{T_K-273}{5}}$

$T_C=\dfrac{5(T_F-32)}{9}\ \to\ \boxed{T_C=\dfrac{5}{9}(T_F-32)}$

$T_C=T_K-273\ \to\ \boxed{T_K=T_C+273}$

$T_F=10\ºC\ \to\ T_C=\dfrac{5}{9}(10-32)=-\dfrac{110}{9}\ \to\ \boxed{T_C\approx-12.222\º C}$

$T_K\approx-12.222+273=\dfrac{2347}{9}\ \to\ \boxed{T_K\approx260.778\ K}$
