Isothermal processes are of special interest for ideal gases. This is a consequence of Joule's second law which states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. [4] Thus, in an isothermal process the internal energy of an ideal gas is constant. This is a result of the fact that in an ideal gas ...
v. t. e. Isothermal flow is a model of compressible fluid flow whereby the flow remains at the same temperature while flowing in a conduit. [1] In the model, heat transferred through the walls of the conduit is offset by frictional heating back into the flow. Although the flow temperature remains constant, a change in stagnation temperature ...
Isothermal Kovats retention index. The Kovats index applies to organic compounds. The method interpolates peaks between bracketing n -alkanes. The Kovats index of n-alkanes is 100 times their carbon number, e.g. the Kovats index of n - butane is 400. The Kovats index is dimensionless, unlike retention time or retention volume.
In chemical thermodynamics, isothermal titration calorimetry (ITC) is a physical technique used to determine the thermodynamic parameters of interactions in solution. [1] [2] It is most often used to study the binding of small molecules (such as medicinal compounds) to larger macromolecules ( proteins , DNA etc.) in a label-free environment.
Isothermal transformation diagrams (also known as time-temperature-transformation ( TTT) diagrams) are plots of temperature versus time (usually on a logarithmic scale ). They are generated from percentage transformation-vs time measurements, and are useful for understanding the transformations of an alloy steel at elevated temperatures. An ...

t. e. Thermodynamic diagrams are diagrams used to represent the thermodynamic states of a material (typically fluid) and the consequences of manipulating this material. For instance, a temperature– entropy diagram ( T–s diagram) may be used to demonstrate the behavior of a fluid as it is changed by a compressor.
