Question

A temperatura de determinada supstancia e 50 f. A tenperatura absoluta dessa substancia em kelvins e

Answer 1

A temperatura correspondente a 50º F é de 283 K

As escalas Kelvin e Fahrenheit apresentam como relação entre elas:

$\Large\displaystyle\boxed{\boxed{\sf \dfrac{T_K-273}{5} = \dfrac{T_F-32}{9}}}$

Calculando, temos:

$\Large\displaystyle\text{ {\sf \dfrac{T_K-273}{5} = \dfrac{50-32}{9}} }\\\\\\\Large\displaystyle\text{ {\sf \dfrac{T_K-273}{5} = \dfrac{18}{9}} }\\\\\\\Large\displaystyle\text{ {\sf \dfrac{T_K-273}{5} =2} }\\\\\\\Large\displaystyle{\sf T_K-273 =2\cdot 5}\\\\\\\Large\displaystyle{\sf T_K-273 =10}\\\\\\\Large\displaystyle{\sf T_K =10+273}\\\\\\\Large\displaystyle\boxed{\sf T_K =283 \: K}$
