You have asked the question in a way that reveals that you don't really understand the concepts at play here.
Adding water won't add energy to the food.
The food, if the calories were released into water as heat would heat the water in a predictable way.
A single calorie is the amount of energy that it takes to raise the temperature of water by one degree celsius.
Thus, if you took 100 grams if water at 0 degrees C (still liquid, not ice) and applied the energy it would be enough to raise the temperature to 100 degrees C (still liquid, not boiled to vapor).
Incidentally, 1 physical kcal is also referred to as a Dietician's Calorie. Note that the physical calorie has a small c and the Dietician's Calorie has a capital C. When we talk about a bunch of Oreos having 100 Calories, it equals 100 kcal.
