Two Components: Liquid–Liquid Systems

Two Components: Liquid–Liquid Systems

A pressure-composition phase diagram explicitly describes the behavior of an ideal solution of two volatile liquids under varying pressures and compositions. A pressure-composition diagram has two main curves. The bubble point curve represents the plot of pressure versus liquid mole fraction. It indicates the pressure at which the first bubble of vapor forms from the liquid phase as the system pressure decreases.The dew point curve is the pressure versus vapor mole fraction. It indicates the...

Phase Transitions: Melting and Freezing

Phase Transitions: Melting and Freezing

Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Intermolecular Forces in Solutions

Intermolecular Forces in Solutions

The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Liquid–Solid Solutions

Liquid–Solid Solutions

The process of a solid dissolving in a liquid to form a solution is governed by the solubility limit, which is the maximum amount of the solid substance, or solute, that can be dissolved in a specific volume of the liquid or solvent. As the solute dissolves, it reaches a point where no more solute can be dissolved at a given temperature - this is known as the saturation point. However, if further solute is added and it manages to dissolve, the solution becomes supersaturated. Supersaturated...

Molecular and Ionic Solids

Molecular and Ionic Solids

Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Nonideal Two-Component Liquid Solutions

Nonideal Two-Component Liquid Solutions

Nonideal liquid solutions, also known as real solutions, do not strictly follow Raoult's law. Raoult's law is a rule of thumb in physical chemistry. However, not all mixtures adhere to this law due to varying molecular interactions. For example, in an acetone/chloroform solution, the individual vapor pressures of the components are lower than expected, resulting in a total vapor pressure below that predicted by Raoult's law, causing a negative deviation.On the other hand, in an ethanol/water...

Summary

Diffusivity in liquids scales with excess entropy, but deviations signal glass formation. Crystallizing liquids differ by triggering solidification when cooperative dynamics emerge.

Background:

Diffusivity in liquids is crucial for understanding phase transitions.
Entropy contributions (excess, pair, residual multiparticle) influence liquid dynamics.
Lennard-Jones liquids and binary glassformers serve as model systems.

Purpose of the Study:

To examine relationships between diffusivity and entropy contributions in various liquids.
To differentiate dynamics of crystallizing versus vitrifying liquids.
To identify markers for glass transition and crystallization onset.

Main Methods:

Analysis of Lennard-Jones liquids and binary glassformers.
Application of approximate inverse power law mappings.
Investigation of Rosenfeld-type excess entropy scaling.
Examination of single-particle mean square displacement and spatiotemporal heterogeneity.

Main Results:

Rosenfeld-type excess entropy scaling holds for both crystallizing and vitrifying liquids in dense phases.
Deviations from scaling and increased heterogeneity mark glassformer dynamics.
Crystallizing liquids initiate solidification with cooperative dynamics under specific conditions.

Conclusions:

Excess entropy scaling is a universal descriptor for liquid diffusivity.
Local cooperative dynamics and caging effects distinguish glass vs. crystal formation.
Isomorph-invariant properties link entropy, diffusivity, and correlation functions.
