Question

A fusão do mercurio sólido ocorre a -39 °c. Qual é a temperatura correspondente nas escalas de Fahrenheit e kelvin?

Answer 1

Na escala Fahrenheit

°F = (C × 1,8) + 32

°F = (-39 × 1,8) + 32

°F = - 70,2 + 32

°F = - 38,2

Na escala Kelvin

K = 273,15 - °C

K = 273,15 - 39

K = 234,15

Answer 2

Bom Dia!

Escala Fahrenheit;

$\frac{TC}{5}=\frac{TF-32}{9}$

$\frac{-39}{5}=\frac{TF-32}{9}$

$\frac{-7,8}{1}=\frac{TF-32}{9}$

$\mathrm{-70,2}=\mathrm{TF-32}$

$\mathrm{-TF}=\mathrm{-32+70,2}$

$\mathrm{-TF}=\mathrm{-32+70,2}$

$\mathrm{-TF}=\mathrm{38,2}(-1)$

$\mathrm{T}=\mathrm{38,2}^{\circ}F$

___________________________________________

Na escala  kelvin;

TK-273=TC

TK-273=-39

TK=-39+273

T=234°K
