Question

A )Quanto vale 40f na escala celsius B) quanto vale 200f nas escolas kelvin e celsius C) quanto vale 80c na escala Fahrenheit Me ajudem pfv precisa dos cálculos.

Answer 1

a)Tc/5 = Tf-32/9
Tc/5 = 40-32/9
Tc/5 = 8/9
9Tc = 40
Tc = 40/9
Tc= 4,4ºC

b)Tc/5 = Tf-32/9
Tc/5 = 200-32/9
Tc/5 = 168/9
9Tc = 840
Tc= 840/9
Tc= 93,3ºC

Tf/32 = K-273/5
200/32 = K-273/5
1000 = 32K-8736
-32K = -8736-1000
-32K = 9736
K = 9736/32
K = 366,483K

c)Tc/5 = Tf-32/9
80/5 = Tf-32/9
720 = 5Tf-160
-5Tf = -160-720
-5Tf =- 880
Tf = 880/5
Tf = 176ºF

Espero ter ajudado!
