Journal of Molecular Liquids, 2020Co-Authors: William E. Acree, Jennifer HuangAbstract:Abstract A polemic is given regarding the Thermodynamic mixing properties reported in the paper by Liu and coworkers. The authors' calculated Thermodynamic mixing properties were found to be internally inconsistent, and do not obey the standard Thermodynamic Relationship that ∆mixG = ∆mixH − T ∆mixS.

Comment on “Solubility determination and correlation of cyromazine in sixteen pure solvents and mixing properties of solutions”
Fluid Phase Equilibria, 2019Co-Authors: William E. AcreeAbstract:Abstract The numerical values of the logarithm of the infinite dilution activity coefficient, ln γ 1 ∞ , and excess partial molar excess enthalpy at infinite dilution, H 1 E , ∞ , calculated by Zhang and coworkers are not Thermodynamically consistent with each other. The calculated values do not obey the standard Thermodynamic Relationship that the variation in ln γ 1 ∞ with 1/T must be equal H 1 E , ∞ divided by the universal gas constant.

comments on solubility and Thermodynamic properties of maltol in different pure solvents
Journal of Molecular Liquids, 2018Co-Authors: William E. AcreeAbstract:Abstract Errors are discovered in the tabulated Thermodynamic properties of dissolution reported by Li and coworkers. Specifically, the properties do not obey the standard Thermodynamic Relationship of ΔdissG = ΔdissH − T ΔdissS, where ΔdissG, ΔdissH and ΔdissS are respectively the Gibbs energy of dissolution, the enthalpy of dissolution, and the entropy of dissolution of maltol in the organic solvent at the solution temperature, T.

the Thermodynamic Relationship between the rn ads black holes and the rn black hole in canonical ensemble
Advances in High Energy Physics, 2017Co-Authors: Lichun Zhang, Jian Liu, Ren Zhao, Shuo CaoAbstract:In this paper, by analyzing the Thermodynamic properties of charged AdS black hole and asymptotically flat space-time charged black hole in the vicinity of the critical point, we establish the correspondence between the Thermodynamic parameters of asymptotically flat space-time and nonasymptotically flat space-time, based on the equality of black hole horizon area in the two different types of space-time. The Relationship between the cavity radius (which is introduced in the study of asymptotically flat space-time charged black holes) and the cosmological constant (which is introduced in the study of nonasymptotically flat space-time) is determined. The establishment of the correspondence between the Thermodynamics parameters in two different types of space-time is beneficial to the mutual promotion of different time-space black hole research, which is helpful to understand the Thermodynamics and quantum properties of black hole in space-time.

contrasting the responses of extreme precipitation to changes in surface air and dew point temperatures
Climatic Change, 2019Co-Authors: Wei Zhang, Gabriele Villarini, Michael WehnerAbstract:The Clausius–Clapeyron (C–C) Relationship is a Thermodynamic Relationship between saturation vapor pressure and temperature. Based on the C–C Relationship, the scaling of extreme precipitation with respect to surface air temperature (i.e., extreme precipitation scaling) has been widely believed to quantify the sensitivity of these extremes to global surface warming under climate change. However, the extreme precipitation scaling rate in the observations produces counter-intuitive results, particularly in the tropics (i.e., strong negative scaling in the tropical land) possibly associated with limitations in moisture availability under the high-temperature bands. The trends in extreme precipitation based on station data are mixed with decreases in most of the tropics and subtropics and increases in most of the USA, western Europe, Australia, and a large portion of Asia. To try to reconcile these results, we examine the extreme precipitation scaling using dew point temperature and extreme precipitation and compare these results with those obtained from surface air temperature and extreme precipitation using station-based data, reanalysis data, and climate model simulations. We find that this mix of increases and decreases in the trends of extreme precipitation across the planet is more similar to the changes in surface dew point temperature rather than the actual temperature across the station-based data, reanalysis data, and the historical experiments with the National Center for Atmospheric Research (NCAR) Community Atmosphere Model, version 5 (CAM5). These findings suggest that dew point temperature is a better and more realistic metric for the responses of extreme precipitation to temperature increases. Therefore, the risk of having extreme precipitation is higher than what was obtained using surface air temperature, particularly in the tropics and subtropics (e.g., South Asia), areas of the world characterized by extremely high population density and severe poverty.

Thermodynamic investigation of room temperature ionic liquid the heat capacity and standard enthalpy of formation of emies
Thermochimica Acta, 2006Co-Authors: Quan Shi, Lixian Sun, Zhiheng Zhang, Yang JiazhenAbstract:Abstract The molar heat capacities of the room temperature ionic liquid 1-ethyl-3-methylimidazolium ethyl sulfate (EMIES) were measured by an adiabatic calorimeter in temperature range from 78 to 390 K. The dependence of the molar heat capacity on temperature was given as a function of the reduced temperature X by polynomial equations, Cp,m (J K−1 mol−1) = 178.6 + 50.28X + 2.886X2 − 1.362X3 + 0.6616X4 + 7.155X5 [X = (T − 132.5)/54.5] for the solid phase (78–187 K) and Cp,m (J K−1 mol−1) = 376.2 + 25.94X − 3.397X2 − 0.6407X3 + 0.8091X4 + 0.9869X5 [X = (T − 292.5)/97.5] for the liquid phase (195–390 K), respectively. According to the polynomial equations and Thermodynamic Relationship, the values of Thermodynamic function of the EMIES relative to 298.15 K were calculated in temperature range from 80 to 390 K with an interval of 5 K. The glass translation of EMIES was observed at 192.85 K. Using oxygen-bomb combustion calorimeter, the molar enthalpy of combustion of EMIES was determined to be Δ c H m ° = − 5152.6 ± 4.6 kJ mo l − 1 . The standard molar enthalpy of formation of EMIES was evaluated to be Δ f H m ° = − 579.13 ± 0.51 kJ mo l − 1 at T = 298.150 ± 0.001 K.
