Abstract Samples of poly[1–(trimethylsilyl)–1–propyne] were kept for about 4 years in ambient conditions. The permeability and diffusion coefficients examined found to be decreased by 1–2 orders magnitude. To ascertain the nature changes underwent during long‐term storage this polymer, several physicochemical methods applied: positron annihilation, wide‐angle X‐ray diffraction, spin probe, density evaluation. These studies indicated that a decrease free volume more close chain packing took...
We have considered some modernization of the equation state for matter (EOS). This is connected with increasing accuracy EOS that has a wide area applicability including critical region. Our analysis shown it possible to increase such if we prepare special input array. It include heterogeneous reliable data isochore heat capacity, gas and liquid densities ρ−, ρ+ saturation line pressure p. The array be used as an in statistical processing allows calculating adjustable coefficients EOS. set...
This paper deals with a fundamental equation of state (FEOS) for substances. We have suggested new method. It allows constructing FEOS that is based on the scaling theory critical phenomena and describes thermodynamic properties related to liquid gas phases substance in wide range pressures temperatures. In framework methodological approach, we provided: (i) transition virial low density region; (ii) Widom region. The method has been tested example R218. area applicability 0 < ρ/ρc 3.2 133 T...
The work studies the issues associated with construction of equation state (EOS) taking due account substance behavior in critical region and scaling theory phenomena (ST). authors have developed a new version hypothesis; this approach uses following: a) having form Schofield-Litster-Ho linear model (LM) b) Benedek hypothesis. hypothesis has found similar character for number properties (isochoric isobaric heat capacities, isothermal compressibility coefficient) at near-critical isochors...
The paper considers the problem of adolescent and young students' personalities' development in conditions face-to-face distance school learning. scientific novelty study is proposed classification pedagogical technologies according to degree their novelty: modernized technology, combinational progressive technology type, essence which shown its title. A specific model type "Teaching cooperation, a team using flipped classroom" was developed. developed implemented during classes humanities...
A new calculation method is considered for calculating pressure ps and density ρ− of saturated steam, ρ+ liquid the heat vaporization r within temperature range from Tt to Tc, where triple-point temperature, Tc critical temperature. specific feature ability predict ps, ρ−, values even in absence experimental data on particular properties vicinity triple point. The has been tested example computation R1234yf refrigerant 122.6≤T≤367.85 K. For this purpose, R1234yf, basis modified...
Abstract On the basis of Clapeyron equation and scale theory, expressions are developed for “apparent” heat vaporization r * = ( T ), vapor ρ - ) liquid + branches saturation line individual substances range state parameters from triple point p t ,T ,ρ to critical c ). The peculiarity proposed approach description is that all exponents components equations universal up universality indices α, β Δ. In this case, order parameter d s (ρ − )/(2ρ average diameter f 1 satisfy model [2β,1−α], which...
A unified fundamental equation of state 2,3,3,3-tetrafluoropropene (R1234yf) has been developed, a fourth-generation ozone safe refrigerant, and method for constructing the proposed. In gas region, this transforms into virial state, in vicinity critical point it satisfies requirements modern large-scale theory phenomena Widom scale equation. On basis single accordance with GOST R 8.614-2018, standard reference data (GSSSD 380-2020) on density, enthalpy, isobaric heat capacity, isochoric...
