Question

4-Transforme a)40ºC ________ºF b)50ºF ________ºC c)473K________ºF

Answer 1

a) 140°F
b) 10°C
c) 391,73°F

Answer 2

Utilizando a fórmula °C/5 = °F - 32/9 = °K - 273/5, temos:

A)

40/5 = °F - 32/9

8 = °F - 32/9

9.8 = °F - 32

32 + 72 = °F

°F = 104°


B)

°C/5 = 50-32/9

°C/5 = 18/9

°C/5 = 2

°C = 2.5

°C = 10°


C)

°F - 32/9 = 473 - 273/5

°F - 32/9 = 200/5

°F - 32/9 = 40

°F - 32 = 40.9

°F = 360 + 32

°F = 392
