Thermodynamics: Notes
... Some processes, we see, will involve heat flow. In these processes, we want the system to be in equilibrium. So we require a quasistatic process. Thus, every process involving heat flow is to be quasistatic. Further, we have banned dissipative forces from the system. Therefore, these processes are r ...

Entropy change of an ideal gas determination with no reversible
... As is stressed in literature [1], [2], the entropy change, ∆S, during a given irreversible process is determined through the substitution of the actual process by a reversible one which carries the system between the same equilibrium states. This can be done since entropy is a state function. Howeve ...

Different levels of reversibility
... The first law of thermodynamics gives an overall law of energy conservation. Stated simply, the energy of an isolated system remains constant. For any subsystem in the isolated system, the energy change equals the difference between the heat added and the work done. The internal energy of a system d ...
