Thermodynamic potentials

Storyboard

Key thermodynamic potentials include:



Internal Energy: the energy required to form a thermodynamic system, isolated from any external environment.

Enthalpy: the energy needed to form a system and place it within an environment. Enthalpy essentially combines internal energy and the work needed to integrate the system into its surroundings.

Helmholtz Free Energy: the portion of a systems internal energy that is available to perform work at constant temperature.

Gibbs Free Energy: the part of the enthalpy of a system that can be used to perform work under constant temperature and pressure conditions.
