An exergonic process is a type of chemical or physical reaction that releases energy during the reaction. The term "exergonic" is derived from the Greek words "ex-" meaning "out of" and "ergon" meaning "work" or "energy." In an exergonic reaction, the Gibbs free energy of the products is lower than that of the reactants, which means that the reaction can occur spontaneously under suitable conditions.

Apparent molar properties refer to certain thermodynamic properties of a solution that can be associated with the individual components in that solution, adjusted to a standard unit (typically per mole of solute). These properties reflect how the presence of a solute affects the overall behavior of a solution compared to the pure solvent. The concept of apparent molar properties is useful in understanding solutions, especially when discussing colligative properties, activity coefficients, and interactions between solute and solvent molecules.

Electronic specific heat refers to the contribution of electrons to the specific heat capacity of a material, particularly in the context of metals and conductors at low temperatures. Specific heat is a measure of how much heat energy is required to change the temperature of a substance.

Pressure is defined as the force exerted per unit area on a surface. It is a scalar quantity, meaning it has magnitude but no direction. The formula to calculate pressure (P) is: \[ P = \frac{F}{A} \] where: - \( P \) is the pressure, - \( F \) is the force applied, - \( A \) is the area over which the force is distributed.

The Schottky anomaly refers to a specific behavior observed in the heat capacity of certain materials, particularly in ionic or non-metallic solids, at low temperatures. Named after physicist Walter H. Schottky, the phenomenon arises due to the presence of localized states or defects within the material's crystal structure. In these materials, as the temperature decreases, the heat capacity does not follow the expected behavior for standard Debye or Einstein models, which predict a decrease in heat capacity with decreasing temperature.

In thermodynamics, volume refers to the amount of space that a substance (solid, liquid, or gas) occupies. It is a fundamental property of matter and plays a crucial role in understanding various thermodynamic processes and laws. Volume can be measured in different units, depending on the system of measurement used. Common units include cubic meters (m³) in the SI system, liters (L), and milliliters (mL).

Henri Victor Regnault (1810–1878) was a prominent French chemist and physicist known for his significant contributions to the fields of thermodynamics and physical chemistry. He is best known for his work on the properties of gases and the development of the ideal gas law, as well as his studies on the behavior of steam in thermodynamic systems.

I – Shih Liu is a prominent figure in the field of mathematics, particularly known for contributions in areas such as graph theory, combinatorial optimization, and algorithm design. While specifics about Liu's work may vary, typically such mathematicians are recognized for publishing research papers, developing algorithms, or engaging in mathematical education.

Stigmatism, often misspelled as "stigmatism," refers to a visual defect known as astigmatism. Astigmatism is a common refractive error caused by an irregular shape of the cornea or lens in the eye. Instead of having a perfectly rounded shape, the cornea or lens may be shaped more like a football or an egg, which results in light rays being focused at multiple points, rather than converging at a single point on the retina.

Ilya Prigogine (1917–2003) was a Belgian physical chemist and Nobel laureate best known for his work on Nonequilibrium Thermodynamics and complex systems. He made significant contributions to the understanding of thermodynamic processes far from equilibrium, introducing concepts such as dissipative structures, which are ordered structures that arise in systems that are not in equilibrium. Prigogine's work challenged traditional views of thermodynamics, which were primarily concerned with systems at equilibrium.

Julius von Mayer (1814–1878) was a German physicist and one of the key figures in the development of the concept of energy conservation in physics. He is best known for formulating the first law of thermodynamics, which states that energy cannot be created or destroyed, only transformed from one form to another. Mayer's work laid the foundation for the understanding of the relationship between different forms of energy, such as heat and mechanical work.

Richard Sears McCulloh (born 1931) is a notable American mathematician known primarily for his work in functional and harmonic analysis. He has contributed to various fields within mathematics and has been involved in academic teaching and research.

Victor Gustave Robin is a French physician known for his contributions to the field of medicine, particularly in the area of pathology.

A contig, short for "contiguous sequence," is a term commonly used in genomics and bioinformatics. It refers to a set of overlapping DNA segments that collectively represent a consensus sequence of a certain region of a genome. Contigs are formed during the process of assembling a genome from shorter DNA sequences, such as those obtained from sequencing technologies.

Thermodynamic databases for pure substances are comprehensive compilations of thermodynamic properties and data for individual chemical substances. These databases provide essential thermodynamic information that is critical for engineers, scientists, and researchers involved in various fields such as chemical engineering, materials science, thermodynamics, and environmental science. ### Key Features of Thermodynamic Databases: 1. **Properties Catalog**: - **Phase Behavior**: Information on phase changes, including phase diagrams, boiling points, melting points, and critical points.

"On the Equilibrium of Heterogeneous Substances" is a seminal work by the physicist and chemist J. Willard Gibbs, published in 1876. This work is renowned for its foundational contributions to the field of thermodynamics and physical chemistry, particularly in the context of phase equilibria.

The Cheng cycle, also known as the Cheng process, is a thermodynamic cycle that describes the operation of certain types of heat engines and engines designed for specific applications, particularly those involving low-temperature heat sources or waste heat recovery. The cycle includes processes that utilize phase change and often incorporates components such as heat exchangers, compressors, and expanders.

The Edmonds–Karp algorithm is an implementation of the Ford-Fulkerson method for computing the maximum flow in a flow network. It uses a breadth-first search (BFS) approach to find augmenting paths in the residual graph, which helps to ensure that the maximum flow is computed in polynomial time.

The term "level of free convection" typically refers to the degree or intensity of free convection occurring in a fluid. Free convection, also known as natural convection, occurs when fluid motion is caused by the buoyancy forces that arise due to density differences in the fluid, often due to temperature gradients. When a fluid is heated, it becomes less dense and tends to rise, while cooler, denser fluid descends.
