Question

Transforme as seguintes temperaturas em °C:

a) - 200 F
b) 100°F
c) 200 K

Answer 1

A)

$\frac{ - 200 - 32}{9 } = \frac{tc}{5}$

Multiplica cruzado:

$9 \times tc = - 232 \times 5$

$9tc = - 1.160$

$tc = - 1.160 \div 9$

$tc = - 128.88c$

-128,88°C

B)

$\frac{100 - 32}{9} = \frac{tc}{5}$

$\frac{68}{9} = \frac{tc}{5}$

$9 \times tc = 68 \times 5$

$9tc = 340$

$tc = 340 \div 9$

$tc = 37.77c$

37,77°C

C)

$\frac{200 - 273}{5} = \frac{tc}{5}$

$\frac{ - 73}{5} = \frac{tc}{5}$

$5 \times tc = - 73 \times 5$

$5tc = - 365$

$tc = - 365 \div 5$

$tc = - 73c$

-73°C
