Energy changes in reactions
Every reaction moves energy. Some push it out into the room and some pull it in, and a thermometer in the beaker is how you tell which. This unit is about which way the energy goes, why nothing is ever created or destroyed doing it, and how much a leaking beaker costs you when you try to measure it.
