Question

Transformar

(A)5ºC em ºF -

(B)300 ºK em ºC ;

(C)-4 ºF em ºC

Answer 1

$<var>\frac{C}{5}=\frac{F-32}{9}\\\\ C=K-273\\\\\\\\\ \frac{5}{5}=\frac{F-32}{9}\\ 1.9={F-32}\\ 9+32=F\\ F=41\\\\\\ C=300-273\\ C=27\\\\\\ \frac{C}{5}=\frac{-4-32}{9}\\ \frac{C}{5}=\frac{-36}{9}\\ \frac{C}{5}=-4\\ {C}=5(-4)\\ C=-20 </var>$
