Question

transforme 5 graus Fahrenheit em Kelvin

Answer 1

FORMULA: Tk - 273/5 = TF-32/9

Tk - 273/5 = 5-32/9
Tk - 273/5 = 27/9
9TK - 2457 = 135
9TK = 135 + 2457
9TK = 2592
TK =  2592/9
Tk = 288ºK

Answer 2

$\frac{Tf - 32}{9} = \frac{Tk - 273}{5} \\ \\ \frac{5 - 32}{9} = \frac{Tk - 273}{5} \\ \\ \frac{-27}{9} = \frac{Tk - 273}{5} \\ \\ - 135 = 9Tk - 2457 \\ \\ Tk = \frac{2322}{9} \\ \\ Tk = 258 K$
