Question

transforme:
a) 68 ºF em ºC b) 80 ºC em K c) 35 ºc em ºF d) 293 K em ºc

Answer 1

Olá.

A.

$\boxed{F= 1,8*C+32} \\ \\ 68= 1,8*C+32 \\ 68-32= 1,8C \\ 36= 1,8C \\ C= \frac{36}{1,8} \\ \boxed{C= 20}$

B.

$\boxed{K= C+273} \\ \\ K= 80+273 \\ \boxed{K= 353}$

C.

$\boxed{F= 1,8*C+32} \\ \\ F= 1,8*35+32 \\ F= 63+32 \\ \boxed{F= 95}$

D.

$\boxed{K= C+273} \\ \\ 293= C+273 \\ 293-273= C \\ \boxed{C= 20}$

Bons estudos!

Answer 2

a)

$T_C=\frac{5}{9}*T_F-\frac{1}{9}*160$

$T_C=\frac{5}{9}*68-\frac{1}{9}*160$

$\boxed{\boxed{T_C=20^oC}}$

b)

$T_K=T_C+273$

$T_K=80+273$

$\boxed{\boxed{T_K=353~K}}$

c)

$T_F=1.8*T_C+32$

$T_F=1.8*35+32$

$\boxed{\boxed{T_F=95^oF}}$

d)

$T_C=T_K-273$

$T_C=293-273$

$\boxed{\boxed{T_C=20^oC}}$
