For that reason, in thermodynamics, we define two kinds of specific heat: 1. specific heat at constant pressure (cpcp) and 2. specific heat at constant volume (cvcv). As they are considered almost incompressible, and their volume doesn't significantly change, for liquids and solids, cpcp ...
Thermodynamics is studied in the extended phase space where the pressure is proportional to the cosmological constant. First law and the Smarr formula are derived. There are phase transitions similar to the Van der Waals liquid-gas phase transitions. Black hole is also studied as a heat engine ...
They hence outperform fully irreversible engines and have played for this reason a central role in finite-time thermodynamics for forty years2,3. We note that quantum systems generally exhibit internal friction when their Hamiltonian does not commute at different times16,17. We additionally ...
Heat Transfer Engineering Thermodynamics Convection of Known Surface Area CalculatorConvective heat transfer , often referred to simply as convection , is the transfer of heat from one place to another by the movement of fluids . Convection is usually the dominant form of heat transfer in liquids ...
The field (geometrical) theory of specific heat is based on the universal thermal sum, a new mathematical tool derived from the evolution equation in the Euclidean four-dimensional spacetime, with the closed time coordinate. This theory made it possible
meaning they cannot be created or destroyed, only transformed. This was a major breakthrough in developing thermodynamics, the study of energy and its transformations. What are some Applications of the Mechanical Equivalent of Heat? The concept of the mechanical equivalent of heat has many applicatio...

Developing quantum machines which can outperform their classical counterparts, thereby achieving quantum supremacy or quantum advantage, is a major aim of the current research on quantum thermodynamics and quantum technologies. Here, we show that a fast-
