Evaluation of Thermal Effects on the Dissolution of a Nonaqueous Phase Liquid in Porous Media Porous media contaminated with nonaqueous phase liquids (NAPLs) may serve as a long-term source of groundwater contamination. To remove NAPLs and thereby m... PT Imhoff,A Frizzell,CT Miller - 《Envir...
The same thing also occurs in liquids, where atoms and molecules move faster as they glide and flow over one another. Unlike solids, however, liquids expand in all directions since they do not have fixed shapes. Thus, volume expansion is common in liquids, and linear expansion does not ...
2.1Free volume and excess enthalpy in the condensed state The thermalexpansion coefficientα1of many liquids is about 7×l0−4K−1, and that of theglassy state(as well as the crystalline state),αsfor polymers is about 2×10−4K−1. The thermalexpansion coefficient ofthe free volume...
32. The thermal expansion coefficient in liquids,αl, is higher by about a factor of 1.5–4 than in solids32,33,34,35. It is well established thatαlcontains two contributions: a vibrational one, also present in the solid state, and an additional configurational one, being caused by the...
Negative thermal expansion (NTE) is an intriguing physical property of solids, which is a consequence of a complex interplay among the lattice, phonons, and electrons. Interestingly, a large number of NTE materials have been found in various types of functional materials. In the last two decades...
The resonance method was applied to measure shear mechanical properties of liquids, and it has thus been established that such low-viscosity liquids as water, cyclohexane, hexadecane, and dibutyl phthalate possess a shear elasticity of about 10 dyn/cm at a frequency of shear oscillations of about...
In the case of solids and liquids, thermal expansion is associated with the asymmetry (anharmonicity) of the thermal vibrations of the atoms; as a result of this asymmetry, the interatomic distances increase with increasing T. The experimental determination of α and α1 is carried out by the ...
