Question

3.25 kcal is the same amount of energy as

Answer 1

1 cal = 4,185 J
1 kcal = 1*10^3 cal
or
=1000 cal

Answer 2

Answer:

$E = 13.6 kJ$

Explanation:

As we know that

1 cal = 4.18 J

$1 kcal = 10^3 cal$

so we have

$1 kcal = 10^3 \times 4.18 J$

now we have total energy in k cal unit given as

$E = 3.25 kcal$

$E = 3.25 \times 4.18 \times 10^3$

$E = 13585 J$

$E = 13.6 kJ$
