Now, let both of these processes have equal pressure in their final state. crystal reports date to text

Reversible and Irreversible Isothermal Expansion of an Ideal

WebEine adiabatische oder adiabate Zustandsänderung (griechisch α a, deutsch ‚nicht‘ und διαβαίνειν diabaínein ‚hindurchgehen‘) ist ein thermodynamischer Vorgang, bei dem ein System von einem Zustand in einen anderen überführt wird, ohne Wärme mit seiner Umgebung auszutauschen. In diesem Sinne werden adiabat und „wärmedicht“ synonym … WebThis paper aims to contribute to a better understanding of the concepts of a "reversible process" and "entropy". For this purpose, an adiabatic irreversible expansion or compression is analysed, by considering that an ideal gas is expanded (compressed), from an initial pressure P[subscript i] to a final pressure P[subscript f], by being placed in contact with a … WebThe irreversible adiabatic process occurs in the free expansion of gas.
