01:22Enthalpies of Physical Changes
In thermodynamics, the enthalpy of a system reflects the amount of energy contained within it, which can be used to perform work. When we discuss physical changes in a substance, such as a phase transition from solid to liquid or liquid to gas, we often refer to the concept of enthalpy change.The standard enthalpy changes for a reaction or a physical process are defined as the difference in enthalpy between the products in their standard states and the reactants in their standard states, all...
01:26Thermodynamic Potentials
Thermodynamic potentials are state functions that are extremely useful in analyzing a thermodynamic system. They have dimensions of energy. The four important thermodynamic potentials are internal energy, enthalpy, Helmholtz free energy, and Gibbs free energy. These thermodynamic potentials can be expressed using two of the following variables: pressure, volume, temperature, and entropy. These two variables are expressed as the rate of change of the thermodynamic potential with respect to other...
01:18Enthalpy within the Cell
Enthalpy (H) is used to describe the thermodynamics of chemical and physical processes. Enthalpy is defined as the sum of a system's internal energy (U) and the mathematical product of its pressure (P) and volume (V):
H = U + PV
Enthalpy is also a state function. Enthalpy values for specific substances cannot be measured directly; only enthalpy changes for chemical or physical processes can be determined. For processes that take place at constant pressure (a common condition for many chemical...

02:59Enthalpy
Chemists ordinarily use a property known as enthalpy (H) to describe the thermodynamics of chemical and physical processes. Enthalpy is defined as the sum of a system’s internal energy (E) and the mathematical product of its pressure (P) and volume (V):
01:25Enthalpy and Heat Capacity
Enthalpy (H) is a thermodynamic quantity that combines the internal energy of a system with the product of its pressure and volume. It can be mathematically represented as H = U + pV, where U is the internal energy, p is the pressure, and V is the volume. Since energy, pressure, and volume are state functions, enthalpy is also a state function. However, it's important to note that absolute enthalpy values for specific substances cannot be measured. Only the change in enthalpy, denoted as ΔH,...
01:26Enthalpies of Chemical Changes
The enthalpy change of a chemical reaction is the difference between the total enthalpy of the products and the reactants. This energy change for the molecules involved in a chemical reaction can be visualized through an energy diagram, where the lines represent the total enthalpy of the reactants and products, and the gap between them signifies the enthalpy change for the reaction. In an exothermic reaction, the system's enthalpy decreases, whereas it increases in an endothermic reaction.The...
