T-028
Hess's law
Enthalpy is a state function, so reaction paths are interchangeable.
T-029
Standard enthalpies of formation
Reaction enthalpy from tabulated formation values.
T-030
Bond enthalpies
Estimating reaction enthalpy from bonds broken and formed.
T-031
Calorimetry
Measuring heat at constant pressure and at constant volume.
