Calorimetry experiment
Name: ______________________________
When you burn food, the chemical energy in food gets converted into thermal energy.
The more chemical energy the food has in it, the more energy gets converted to thermal
energy.
What is energy transfer?
What is energy transformation?
Explain the Law of Conservation of Energy:
What form of energy is stored in food? ___________________________
Prediction
What type of food below do you think will have the most amount of stored energy? Why do
you think this is?
What type of food below do you think will have the least amount of stored energy? Why do
you think this is?
