The Role of Isothermal Enthalpy Production in Coupled Solute Translocation across the MembraneEnthalpy change is shown to play a crucial in dictating the extent of coupling in the energy transduction and metabolically coupled solute translocation across biomembranes. At certain critical enthalpy values ...
Influence of mushy zone constant on the solid-liquid phase change process modeled by enthalpy-porosity technique In the present work, the effects of mushy zone constant on the melting and solidification processes simulation with enthalpy-porosity technique are investigated. The isothermal melting and sol...
摘要: The standard molar enthalpy of formation of CF 2 = CFCl(g) at 298.15 K derived from new measurements of the energy of combustion of liquid samples of the substance is (505.5 ± 4.7) kJ · mol 1 in satisfactory agreement with two previous indirectly derived values.关键词:...
the entropy of the system may even decrease in a spontaneous reaction, as long as the entropy of the universe increases. The ΔSterm in the above equation is the entropy of the system. The ΔHterm actually hides the change in entropy of the surroundings. In isothermal and constant pressure...

1.Theenthalpy methodwas employed to investigate the phase change process in a latent thermal energy storage(LTES) system using multiple phase change materials(PCMs).采用焓法对组合式相变材料(PCM)储热系统的相变过程进行了数值计算,分析了组合式相变材料中各个PCM组分质量分数的变化对系统储热性能的影响。
The work of expansion in adiabatic process (wadi) is related to work of expansion in isothermal process (wiso) is View Solution An ideal gas expands while the pressure is kept constant. During the process, does heat flow into the gas or out of the gas? Justify you answer. View Solution...
Under isothermal conditions, heat is taken in from the surroundings to maintain the system at constant temperature. Under adiabatic conditions (no heat exchange), heat is taken from the system itself and the temperature decreases. Either way, heat (kinetic energy of molecules), from inside or ...
Glasses are known to undergo spontaneous densification during isothermal annealing. This volume recovery process, which is also an enthalpy recovery process, can be viewed as the collapse of highly disordered sites or 'defects'. We have modelled this physical ageing as a diffusion process in which ...
