Property relations : the Maxwell relations

Thermodynamic properties such as temperature, pressure, volume and entropy are related with each other. Their mutual relations are called property relations or Maxwell relations, and the equations showing property relations …

G vs. H

In this video, we focus our attention to the relation between Gibbs free energy G and enthalpy. Gibbs free energy and enthalpy are closely related. If one has experimental data …

Free energy functions

We can determine the reversibility of the process by looking at the total entropy change. However, total entropy change is not the system property. We need information on the surrounding …

Different derivation of G and F

The physical meaning of free energy is highlighted in this video. The free energies are “free energy”. Thermodynamic free energy is the amount of work that a system can perform. …

Thermodynamic potentials

Thermodynamic potential or fundamental function is a quantity used to represent the state of a system. We have four fundamental functions: internal energy U, enthalpy H, Helmholtz free energy F, …

Summary of week 4

This week you still examined the second law of thermodynamics, focusing on the actual entropy calculations. The third law of thermodynamics is essential for estimation of entropy. The third law …

The week ahead

Welcome to the 5th week of the course. This week, we focus our attention to the free energy functions. With free energies, we can determine the reversibility of the process …
