Question

transformação:

a)2,5Kcal - cal
b)2cal - j
c)6.$10^{-4}$cal - Kcal
d)0,032j - cal
e)2.$10^{5}$Kj - j
f)2,2.$10^{-2}$cal - Kcal
g)5,5.$10^{5}$cal - j
h)35Kcal - j

Answer 1

A
1Kcal ----- 1000 cal
2, 5 Kcal ---- x cal
x = 2500 cal

B
1 cal --- 4,18J
2 cal  -- x 
x = 8,36J

C
1Kcal ----- 1000 cal
X Kcal -----0,0006 cal
X = 0,0000006
X = $6X 10^{-7}$

D 
1 cal ---- 4,18J
x cal --- 0,032J
x = 0.0076 Cal

E
1 KJ ---- 1000J
200000 KJ --- x
$x = 2X10 ^{8}$

F
1Kcal ----- 1000 cal
X cal ---- 0,22Cal
X = $2,2 X10^{-5}$

G
1 cal ---- 4,18J
550000 -- X
$X=2,299X10^{6}$

H
1 KCal --- 4,18 J
35 Kcal  --- x 
X = 146,3J
