Chapter 9. The internal energy of a system changes from an initial value U i to a final value of U f due to heat Q and work W: ΔU = U f -U i = Q - W Q.
Energy Transformations Thermochemistry is the study of energy changes that occur during chemical reactions and changes in state. The energy stored in the.
