Calories in a Kit Kat Bar versus a Banana: Do Bananas Contain The Same Amount Of Calories (Kcal) As A Regular Kit Kat Bar?

However, according to the label of the Kit Kat bars, there are 220 calories in a 45g Kit Kat bar. This suggests that the results of the experiment were affected by experimental error. For instance, when the piece of the Kit Kat bar was tested, much heat escaped while it was being burned since the burning Kit Kat bar was not surrounded by an empty pop can, which would have directed the heat that it was producing toward heating the water (when the banana slice was tested, it was surrounded by a pop can, reducing the amount of escaped heat). This is the most notable factor that could have contributed to a low difference between the initial and the final temperature of the water, and ultimately, a much smaller number of calories than expected.
