For an isochoric process (2.25)CV=(δqdT)V=(dUdT)VU=f(V,T)dU=(∂U∂T)VdV+(∂U∂T)VdT. At constant V, dV = 0 and dU=(∂U∂T)VdT or (dUdT)V=(∂U∂T)V. Substituting the partial derivative for the total derivative in equation (2.25) gives (2.26)CV=(∂U∂...
the particular order of the steps set forth in the specification should not be construed as limitations on the claims. In addition, the claims directed to the method and/or process should not be limited to the performance of their steps in the order written, and one skilled in the art can...
The thermal decompositions of potassium and sodium hydrogencarbonate were investigated; it was established that under special conditions the otherwise one-step thermal decomposition of the two materials becomes a two-step process. The phenomenon involves a change only from the point of view of kinetics...
The different destabilization ofthe electronic states may lead to an isobaric change of the ground-stateelectronic configuration, and the same first-order model paves theway to a simple thermodynamical interpretation of this process. 展开 DOI: 10.1021/ACS.JCTC.0C00443 年份: 2020 ...

Isobaric expansion (IE) engines are a very uncommon type of heat-to-mechanical-power converters, radically different from all well-known heat engines. Useful work is extracted during an isobaric expansion process, i.e., without a polytropic gas/vapour ex
