The relationship between Isentropic and reversible adiabatic processes
(هذه المقالة صدقة جارية لموتي المسلمين ومرضانا فبالرجاء الدعاء بالرحمة والمغفرة لأمواتنا والشفاء العاجل للمرضي) ده كان سؤالي This was my question Why every reversible adiabatic process is isentropic but not every isentropic process is reversible adiabatic? When we say " isentropic process" ,our mind goes to think internal reversible and adiabatic process. It is right but they aren't two faces for one coin. However the relationship is every reversible adiabatic process is necessarily isentropic process. But not every isentropic process is necessarily reversible adiabatic process. That explains to fix entropy values, we have many state First: reversible adiabatic .reversible to make (entropy generation equals zero) What means when I reject heat and absorb it again entropy values don't change. And adiabatic to not making losses or gaining of entropy. Second :To make entropy values fixed we should make balance between the increase and decrease of ent...
