Example of reversible process thermodynamics
Webreversible the process goes the other way as soon as you reverse the applied conditions. Quasistatic and reversible are not the same thing. For example you can mix two gases … WebSep 15, 2009 · An adiabatic process (one which does not generate any heat) from state A to state B is therefore only possible if it is entropy increasing: S Θ (A) ≤ S Θ (B).. This definition, of thermodynamic entropy, depends upon cyclic processes that can reach the equality, which are called reversible processes. The existence of such processes …
