Calculate the thermal efficiency of the two reversible cycles True or False; When a net amount of work is done on a closed system undergoing an internally reversible process, a net heat transfer of energy from the system also occurs.
We investigate the equation of state and elastic properties of hcp iron at high pressures and high temperatures using first principles linear response linear-muffin-tin-orbital method in the generalized-gradient approximation. We calculate the Helmholtz free energy as a function of volume, temperature,...

The equation is derived from a fundamental equivalent resistive-circuit model for general thermal conductivity problems. Constants were added to the equation to improve the regression-fit for the resistive model. The equation determines thermal conductivity values for the full range of densities and ...
As an experimental study for balancing daily human comfort and energy saving, this paper describes a structural equation modeling for questionnaire data. The goal is to clarify the causal relation among thermal comfort and thermal sensation of body parts. The experimentation data include 22 experimental...
and calculate quantiles from these realizations at each grid-point to give probabilistic regional sea-level change. The provenance of each sea-level component, its associated fingerprint and time dependent global projection (including PDFs) are described in Jackson and Jevrejeva27. For RCP8.5, we ...
In this approach the two-photon master equations can be directly and conveniently converted into c-number partial differential equations. As an example, we solve the typical master equation for two-photon process in some limiting eases.关键词: thermal entangled state master equation ...
Releasing constrains of the chemical bonds in the glass require a transformation of the thermal energy into the mechanical energy. By equating the mechanical and thermal energies, an equation could be obtained to calculate the glass transition temperature T g . The obtained equation shows that the ...
A generalized equation, is derived to calculate the molal latent heat of vaporization, λ, of any substance at any reduced tem-perature, Tr , and reduced pressure, pr, with an error generally less than 5%. P. L. CHU S. S. CHIN Chekiang University, Hangchow, China - 《》 被引量: ...
