a) 50C em K

Tk = Tc + 273
Tk = 50 + 273
Tk = 323K

b)842F em K

Tf - 32 = 1,8Tc
1,8Tc = 842 - 32
1,8Tc = 810
Tc = 810/1,8
Tc = 450ºC

Tk = Tc + 273
Tk = 450 + 273
Tk = 723K

C

Tf - 32 /9 = Tc/5
Tf - 32 /9 = -30/5
Tf - 32 /9 = -6
Tf - 32 = -54
Tf = -54 + 32
Tf = -22ºF

D

Tk = Tc + 273
Tk = -10 + 273
Tk = 263K

E

Tf - 32 /9 = Tc/5
-31 - 32/9 = Tc/5
-63/9 = Tc/5
-7 = Tc/5
Tc = 5 . -7
Tc = -35ºC
