Answer:
If you have 8 Joules of energy that means you have 1.912 calories.
Explanation:
As we know that one calorie is equal to 4.184 J. We need to calculate in 8 Joules of energy how many calories are present.
We know that,
For 1 calorie = 4.184 J
For ? = 8 Joules
To obtain calories in 8 Joules. Divide 8 by 4.184.
calorie=1.912
Therefore, 8 J = 1.912 calorie.
