Reversible process is a process carried out in such a way that at every instant, the system deviation is only infinitesimal from the thermodynamic state, and also which can be reversed in direction and the system retraces the same equilibrium states. Thus in reversible process, the interactions betw ...

... Irreversible Process An irreversible process cannot return both the system and the surroundings to their original conditions if reversed. For example, an automobile engine does not give back the fuel it took to drive up a hill as it coasts down the hill to its original position. There are factors th ...

Heat Engines, Entropy, and the Second Law of Thermodynamics P
... statement of the second law specifies that the energy removed from the gas to return the temperature to its original value cannot be completely converted to mechanical energy in the form of the work done by the engine in compressing the gas. Thus, we must conclude that the process is irreversible. W ...

THE FIRST LAW OF THERMODYNAMICS 3·5 So far we have
... The negativ e sign is due to the sign conven tion that work done on a system is negative. This ensures that work done on a system increas es the energy of the system and work done by a system decreas es it. Now let us replace the electric heater with a paddle wheel (Fig. 3-50). As a result of the st ...

Polytropic Process
... If the volume compresses (delta V = final volume - initial volume < 0), then W < 0. That is, during isobaric compression the gas does negative work, or the environment does positive work. Restated, the environment does positive work on the gas. If the volume expands (delta V = final volume - initial ...
