(a)
Interpretation:
Energy unit conversion needs to be done between kcal and cal.
Concept Introduction:
The Calorie and calorie are different from each other by their definition. Calorie is kilocalorie and the unit is represented as kcal or Cal. Similarly, calorie is represented as cal.
The following conversion factor can be used:
