(2) Work in thermodynamics is a generalization of the concept of work in mechanics as expressed in differential form in equation (2). The generalized coordinates in thermodynamics are the external parameters of a thermodynamic system. Examples are the system’s position in space and volume and th...
The last term might have contributions to Lamb shift corrections in Markovian dynamics8. We can rewrite equation (1) as where Unlike and , the interaction Hamiltonian is a nonlocal operator, that is, it cannot be assigned exclusively to either of subsystems S and B alone. It thus may seem...
A thermodynamic internal variable model for the partition of plastic work into heat and stored energy in metals The energy balance equation for elastoplastic solids includes heat source terms that govern the conversion of some of the plastic work into heat. The remai... P Rosakis,AJ Rosakis,G...
(seedifferential equation), while the corresponding incremental changesd′Qandd′Win heat and work are not, because the definiteintegralsof these quantities are path-dependent. These concepts can be used to great advantage in a precise mathematical formulation of thermodynamics (see belowThermodynamic ...
The equation for the rate of energy consumed by the heart was derived from the general energy equation of thermodynamics. Previous estimates of mechanical efficiency, heat loss, kinetic energy and flow work were shown to be valid. Estimates were made of the "order of magnitude" of those terms...
In your first post you already figured out, that for step (3) ΔW=0: To be able to reach the initial state again, there must be one step where the energy difference of the gas is positive and one step where it is negative. Your equation treats both steps like energy losses. To ...

Equation (19) is a generic form for the efficiency of any engine working in a cycle. In the case of a reversible cycle the second term on the right hand side vanishes and it simply reduces to Eq. (16). Now as is clear from Eq. (19) the second term on the right hand side shows...
