The phrase "at a fixed temperature" is correct and usable in written English.
You can use it when discussing scientific experiments, processes, or conditions that require a specific temperature to be maintained.
Example: "The reaction must be conducted at a fixed temperature to ensure accurate results."
Alternatives: "at a constant temperature" or "at a stable temperature."
In addition, the removal of latent heat in foods during freezing does not occur at a fixed temperature.
In other words, the shear stress divided by the rate of shear strain is constant for a given fluid at a fixed temperature.
Central to the following discussion of entropy is the concept of a heat reservoir capable of providing essentially limitless amounts of heat at a fixed temperature.
In these experiments, the catalyst is applied to a flat surface that is held at a fixed temperature.
As such, gel-to-sol transition could be accomplished by either temperature decrease or exposure to UV irradiation at a fixed temperature lower than the CGTUV.
The Arrhenius blending rule was found applicable to describing the composition dependence of viscosity all vegetable oils diesel blends at a fixed temperature.
The model is applied to predict the heat exchange rate between the liquid and a hot wall kept at a fixed temperature.
At a fixed temperature the crystallization rate of PET decreased with increase in φPVF2 φPVF2=volume fraction of PVF2) in the blend.
This approach is developed for an irreversible, nth-order chemical reaction, A → B occurring exothermically in a closed spherical vessel, whose wall is held at a fixed temperature.
Relative merits of these mechanisms are examined by considering the changes in the orientation polarization and entropy observed on changing the temperature, and observed on spontaneous structural relaxation at a fixed temperature.
These values were generated at a fixed temperature.
