Question

transforme a seguinte escala:

a)2 °C para °F
b)-2 °F para K
c)2 K para °C

Answer 1

veja essa formula$tf=168/5$
$\frac{tc}{5} = \frac{tf-32}{9} = \frac{tk-273}{9}$
a)
$\frac{tc}{5} = \frac{tf-32}{9}$
$\frac{2}{5} = \frac{tf-32}{9}$
$18=5tf-160$
$5tf=18+160$
$5tf=168$
$tf=168/5=33,6$

b)$\frac{tf-32}{9} = \frac{tk-273}{5}$
$\frac{-2-32}{9} = \frac{tk-273}{5}$
$\frac{-34}{9} = \frac{tk-273}{5}$
$9tk-2457=170$
$9tk=170+2457$
$tk=2627/9=291,89$

c)
tk=273+tc
tc=tk-273
tc=2-273=-271
