Specific Heat and Thermal Energy Transfer, Sec. You should also be able to work problems such as Example 6.2 and 6.3, Exercise 6.3 and 6.4. Energy and Changes of State, Sec. You should also be able to use these values in calculations involving state changes. Enthalpy Changes for Chemical Reactions, Sec.
Chemical reactions can be either endothermic or exothermic.
Hess's Law, Sec. 6.7. State Functions, Sec. You should understand that enthalpy is a state function. In other words is only dependent on the final and initial states, not the pathway between these states. Volume is another state function.
