THERMODYNAMIC POTENTIALS

Thermodynamic Potentials

• Thermodynamic potentials are numbers that show how much energy is stored in a system.
• Potentials are a way to measure how much energy moves in a system from its starting point to its ending point.
• Depending on the limits of the system, like temperature and pressure, different potentials are used.
• Thermodynamic potentials are quantities that capture the energy state of a system.
• Different potentials are relevant depending on the system's constraints, like temperature and pressure.
• Each potential tells us something different about the energy transfer within the system.

     Here is a list of different types of thermodynamic potentials and their formulas:

Internal Energy 
Helmholtz free energy F = U - TS
Enthalpy H = U + PV 
Gibbs Free Power G = TS - U + PV

• The list of potentials and their formulas is also accurate.
• Internal energy (U) represents the total energy contained within the system.
• Helmholtz free energy (F) tells us the capacity for work at constant temperature and volume.
• Enthalpy (H) describes the energy available for work at constant pressure.
• Gibbs free energy (G) indicates the spontaneous direction of change in a system at a constant temperature and pressure.
