Day 5:. Check and go over sig fig worksheet Pg 1 in Chapter 2 packet Energy Notes **Element Quiz FRIDAY!!**. Energy Notes:. Energy Heat transfer and Heat Law of Conservation of Energy Heat and Temperature Exothermic/Endothermic. What is Energy?. Energy: the capacity to do work
Energy TRANSFER is always involved when there is a change in matter
Energy is never created or destroyed in a change of matter – just transferred
Notice that the energy of the reactants and products increases, while the energy of the surrounding decreases. However the total energy does not change.
Heat is always transferred in a very specific way:
High Energy to Low Energy.
