Hand Warmer Calorimetry
The design that I am submitting is for a hand warmer. Hand warmers can be extremely
helpful to many people, especially those who live in cold climates. There were 6 salts that I
tested to see which one would make the best
Energy density = (energy released from fuel) / (volume of fuel consumed)
Specific energy = (energy released from fuel) / (mass of fuel consumed)
Efficiency = 100 X (useful output energy) / (total input energy)
Number of carbon atoms
