Question

A fusão do mercurio solido ocorre a -39°C qual é a temperaturacorrespondente nas escalas fahrenheit e kelvin

Answer 1

Resolução da questão, veja:

Conversão de -39 ºC para ºF, observe:

$\dfrac{\°C}{5} = \dfrac{\°F-32}{9}}\\\\\\\\\\ \dfrac{-39}{5} = \dfrac{\°F-32}{9}}\\\\\\\\ 5\cdot(\°F-32) = -351\\\\\\\\ 5\°F -160 = -351\\\\\\\\ 5\°F = -351 + 160\\\\\\\ 5\°F = -191\\\\\\\\ \°F = \dfrac{-191}{5}}\\\\\\\\\ \large\boxed{\boxed{\boxed{\boxed{\boxed{ \°F = -38,2.}}}}}}}}}$

Ou seja, -39 °C equivale à -38,2 °F.

Conversão de -39 °C para K, observe:


$\Theta{K} = \Theta{\°C} + 273,15\\\\\\\\ \Theta{K} = -39 + 273,15\\\\\\\ \large\boxed{\boxed{\boxed{\boxed{\boxed{ \Theta{K} = 234,15.}}}}}}}}}}$

Ou seja, -39 °C equivale à 234,15 K.

Espero que te ajude :).
