Question

tranforme 2F em C° façam o cálculo pfv

Answer 1

Use a fórmula

TC/5 = TF-32/9
TC/5 = 2-32/9
TC/5 = -30/9
TC = -150/9
TC = -16,67 °C

Answer 2

$\frac{C}{5} = \frac{F - 32}{9} \\ C = 5 \times ( \frac{2 - 32}{9} ) = 5 \times (- \frac{30}{9} ) \\ C = 5 \times ( - \frac{10}{3} ) = - \frac{50}{3} \\\boxed{ C≈ - 16.67 {}^{o} C}$
