Measuring Energy
This is a particular method that measures energy in a peanut. A peanut burns producing an impressive amount of flame for a long time. The flame is used to boil away water and count the calories contained in the peanut.
Equation for calculating the calories in a peanut: To raise the temperature of 10 grams of water from 20 °C to 100 °C it takes:
Q = mcDT
Or, use the following equation to calculate the calories per gram of the peanut:
calories per gram = (heat gained by water)/(mass lost when peanut burned)
This is another way of doing the experiment.
