    Part B
    Find a snack food. Determine the grams of fat, protein, and carbohydrate in one serving. Determine the number of "food calories" (Cal) per gram of fat, protein, and carbohydrate. Which of these biomolecules has the highest number of Cal/gram?

    Now based on this information, which is the best energy storage form for the body?

    1Cal = 1000 cal 1 cal = 4.184 J. How many Joules are there in one serving of your snack?

    Water has a specific heat of 4.184 J/g ºC. How many grams of water can be warmed 1 ºC by a serving of your food?
