Comparison of the energy content of different food's
Aims: to compare the energy contents of different foods and make a detailed conclusion and analysis.
Results:
Starting temperature of water in each boiling tube: 23ºc
FoodMass before heating (Grams)Highest temperature of water (ºc)
Toasted Bread2.1832
Cracker0.8945
Chip0.6352
Pistachio0.3590
Almond1.0067
Peanut0.9192
Calculations:
Start temperature of the water x Highest temperature of water x 4.2= Energy Level
(ºC) (ºC) (J)
Toasted bread: 23 x 32 x 4.2= 3091.2 J= 3.0912 kJ
Cracker: 23 x 45 x 4.2= 4347 J= 4.347 kJ
Chip: 23 x 52 x 4.2= 5023.2 J= 5.0232 kJ

…showed last 75 words of 411 total…because I was predicting the normal peanut due to its greasiness. I think that my experiment went extremely well as I did not make any errors and was one of the first in the class to finish. If I were to do this experiment again I would hope to use a calorimeter in order keep a steady supply of oxygen and heat. My calorimeter also might help me make sure the food it fully combusted.
