The thermodynamic square (also known as the thermodynamic wheel, Guggenheim scheme or Born square) is a mnemonic diagram attributed to Max Born and used to help determine thermodynamic relations. Born presented the thermodynamic square in a 1929 lecture. [1] The symmetry of thermodynamics appears in a paper by F.O. Koenig. [2]
The thermodynamic square can be used as a mnemonic to recall and derive these relations. The usefulness of these relations lies in their quantifying entropy changes, which are not directly measurable, in terms of measurable quantities like temperature, volume, and pressure.
The thermodynamic square can be used as a tool to recall and derive some of the thermodynamic potentials based on conjugate variables. In the above description, the product of two conjugate variables yields an energy. In other words, the conjugate pairs are conjugate with respect to energy.
The thermodynamic square can be used as a tool to recall and derive some of the potentials. Just as in mechanics, where potential energy is defined as capacity to do work, similarly different potentials have different meanings like the below: Internal energy (U) is the capacity to do work plus the capacity to release heat.
The first and second law of thermodynamics are the most fundamental equations of thermodynamics. They may be combined into what is known as fundamental thermodynamic relation which describes all of the changes of thermodynamic state functions of a system of uniform temperature and pressure.
Gibbs free energy is a thermodynamic state function that measures the energy available for a system to do work, and is given by the formula G = H – TS, where H is enthalpy, T is temperature, and S is entropy.
Average cost: $1.50 to $5.00 per square foot. It’s simple thermodynamics: heat moves from warmer areas to colder ones. So, whether the goal is to keep that heat inside in the winter, or outside ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
