Question

- Realize as conversões termométricas indicadas.
a) -13 °F→ °C
b) 270,5 K → °C
c) 59 °F →K
d) 23 °F → °C
e) 35,5 °C → °F
​

Answer 1

Resposta:

$\frac{c}{5} = \frac{f - 32}{9}$

$c = k - 273$

a) Tc/5=(-13-32)/9

Tc/5=(-45)/9

Tc.9=(-45).5

9Tc=-225

Tc=-225/9

Tc=-25°C

b)Tc=270,5-273

Tc=-4,5°C

c)primeiro faremos de Tf para Tc

Tc/5=(59-32)/9

Tc/5=27/9

Tc.9=27.5

9Tc=135

Tc=135/9

Tc=15°C

Tk=Tc+273

Tk=15+273

Tk=288K

d)Tc/5=(23-32)/9

Tc/5=-9/9

Tc.9=-9.5

9Tc=-45

Tc=-45/9

Tc=-5°C

e)35,5/5=(Tf-32)/9

35,5.9=(Tf-32).5

319,5=5Tf-160

319,5+160=5Tf

479,5=5Tf

Tf=459,5/5

Tf=95,9°F
