…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.
