Answer 1

Fórmulas
Celsius/Kevin = K = C + 273
Celsius/Fahrenheit = $\frac{C}{5} = \frac{F-32}{9}$

a) K = 80 + 273 = 353K

b) $\frac{15}{5} = \frac{F-32}{9}$
15 . 9 = 5(F-32)
135 = 5F - 160
5F - 160 = 135
5F = 135 + 160
5F = 295
$F = \frac{295}{5}$
F = 59ºF

c) 175 = C + 273
C + 273 = 175
C = 175 - 273
C = -98ºC

d) $\frac{C}{5} = \frac{79-32}{9}$
9C = 5(79-32)
9C = 395 - 160
9C = 235
C = $\frac{235}{9}$
C ≈ 26,1ºC

e) 300K = C + 273
C + 273 = 300
C = 300 - 273
C = 27ºC
$\frac{27}{5} = \frac{F-32}{9}$
27 . 9 = 5(F-32)
243 = 5F - 160
5F - 160 = 243
5F = 243 + 160
5F = 403
F = $\frac{403}{5}$
F = 80,6ºF

f) $\frac{C}{5} = \frac{50-32}{9}$
9C = 5(50-32)
9C = 250 - 160
9C = 90
C = $\frac{90}{9}$
C = 10ºC

g) $\frac{40}{5} = \frac{F-32}{9}$
40 . 9 = 5(F-32)
360 = 5F - 160
5F = 360 + 160
5F = 520
F = $\frac{520}{5}$
F = 104ºF

h) 290 = C + 273
C + 273 = 290
C = 290 - 273
C = 17ºC

Answer 2

Resposta:

Bom dia!

Explicação:

Fórmula de conversão:

• C ⇒ K ou K ⇒ C ║ $K = C + 273$

• C ⇒ F ou F ⇒ C ║ $F = 1,8C + 32$

A)80°c P/Kelvin

$K = C + 273\\\\K = 80 + 273\\\\K=353$

B)15°c P/ Fahrenheit

$F = 1,8C + 32\\\\F = 1,8*15 + 32\\\\F = 27 + 32\\\\F=59$

C) 175 k P/Celsius

$K = C + 273\\\\175 = C + 273\\\\C=175-273\\\\C=-98$

D) 79 Fahrenheit P/ Celsius

$F = 1,8C + 32\\\\79 = 1,8C + 32\\\\1,8C =79- 32\\\\C=47/1,8\\\\C=26,1$

E) 300K P/ Fahrenheit

C + 273 = 300

C = 300 - 273

C = 27

27 . 9 = 5(F-32)

243 = 5F - 160

5F - 160 = 243

5F = 243 + 160

5F = 403

F = 403/5

F = 80,6

F) 50 Fahrenheit P/ Celsius

$F = 1,8C + 32\\\\50 = 1,8C + 32\\\\1,8C=50-32\\\\C=18/1,8\\\\C=10$

G) 40°c P/ Fahrenheit

$F = 1,8C + 32\\\\F = 1,8*40 + 32\\\\F =72+ 32\\\\F=104$

H) 290k P/ Celsius

$K = C + 273\\\\290 = C + 273\\\\C=290-273\\\\C=17$
