With the Designing a Hand Warmer Inquiry Lab Kit for AP® Chemistry, students investigate energy changes and calorimetry with formations of solutions. Students challenge themselves to design the best, all-around hand warmer.
The Hand Warmer Design Challenge by Jason Santana on Prezi
What substance creates the best handwarmer? In order to test which substance will be the most efficient, calorimetry must be used. Calorimetry is the measurement of the amount of heat evolved or absorbed in a chemical reaction, change of state, or formation of a solution. Well
