Heating and Cooling Curves
0 Views •
2020
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves. For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

We present a parametric driving method to cool an ultracold Fermi gas in a crossed-beam optical dipole trap. This method selectively removes high-energy atoms from the trap by periodically modulating the trap depth with frequencies that are resonant with the anharmonic components of the trapping potential.

Here, we present a protocol to demonstrate the generation of ice when water is introduced to a cold bath of brine, as a secondary refrigerant, at a range of temperatures well below the freezing point of water. It can be used as an alternative way of producing ice for industry.
FAQs
The achievable temperature of a cooling bath depends on its composition and phase equilibrium. These features determine which phase changes can occur and how stable the bath remains while it absorbs heat. Consequently, two mixtures intended for cooling may provide different temperature ranges or stability, so bath selection must match the reaction or sample’s required conditions.
Melting and sublimation improve heat removal by absorbing latent heat, the energy required for a phase change without an immediate temperature increase. This mechanism allows a bath to take up thermal energy while helping maintain a relatively controlled environment. Its usefulness depends on whether the selected composition undergoes the relevant phase transition under the experimental conditions.
Thermal contact determines how effectively heat moves between the vessel and the cold medium. Poor contact can limit cooling even when the bath itself is cold, whereas appropriate contact supports more consistent temperature control. Composition, phase equilibrium, and ongoing temperature monitoring therefore influence both bath stability and the reproducibility of the chemical process.
To use a cooling bath, researchers select a composition suited to the desired temperature and place the reaction vessel, sample, or equipment in thermal contact with the cold medium. They then monitor the bath temperature while the process proceeds. This workflow helps maintain the intended conditions and provides an opportunity to detect changes that could compromise safety or reproducibility.
Cooling baths are useful when an experiment must remove heat or limit temperature changes. In chemistry, they can control exothermic reactions, slow temperature-sensitive processes, promote crystallization, and support low-temperature distillation or sample handling. The appropriate application depends on the thermal conditions required, rather than on cooling alone.
During an exothermic reaction, controlled cooling can help prevent excessive temperature increase and runaway behavior. For temperature-sensitive materials, it can reduce the risk of product degradation; during crystallization, it can help establish conditions that favor the process. These outcomes make bath choice and temperature monitoring relevant to both experimental safety and consistent results.
