Question

A temperatura em um ambiente é 40°C. Qual será a leitura na escala Fahrenheit? Dados: ºF = ºC x 1,8 + 32
104°F
98°F
100°F
132°F ​

Answer 1

$\boxed{\dfrac{T_C}{5}=\dfrac{T_F-32}{9}=\dfrac{T_K-273}{5}}$

$\Longrightarrow T_F-32=\dfrac{9T_C}{5}\Longrightarrow \boxed{T_F=1.8T_C+32}$

$T_C=40^{\circ}\text{C}\Longrightarrow T_F=1.8(40)+32=72+32\ \therefore\ \boxed{T_F=104^{\circ}\text{F}}$
