Heat and EnthalpyThis is a series of lectures in videos covering topics in General Chemistry. They are conducted by Dr. Chuck Wight who teaches chemistry at the University of Utah.
Heat and Enthalpy This General Chemistry lecture covers the First Law of Thermodynamics. We discuss the equivalence of heat, work and energy, the definitions of thermodynamic state functions, and the relationships between internal energy, enthalpy and heat
Enthalpy Changes for Chemical Reactions General Chemistry lecture covering endothermic and exothermic reactions, Hess Law, bond energies, and standard enthalpies of formation for chemical substances. We also describe the method of calculating the enthalpy of combustion for materials.
Enthalpy of Expansion and Compression of Gases General Chemistry lecture covering the basic transfer of heat and work to and from gases during expansion and compression. We discuss how to compute heat and/or work for isochoric heating, isothermal expansion and adiabatic expansion. We also present a general strategy for determining changes in thermodynamic state functions for arbitrary changes in pressure, volume and temperature for ideal gases.
