WebConditions of Reversibility or Factors Making the Process Irreversible: (i) A process should be quasi-static (ii) There should be no friction (iii) Both the system and the surroundings should restore their initial state after the process is reversed. Carnot Engine and Carnot Cycle: ADVERTISEMENTS: WebDec 6, 2024 · Irreversibility is also demonstrated during this stage and is closely related to the ideas of centration and conservation. Irreversibility refers to the young child’s difficulty mentally reversing a sequence of events. In the same beaker situation, the child does not realize that, if the sequence of events was reversed and the water from the ...

WebApr 22, 2016 · A thermodynamic process is called reversible if an infinitesimal change of the external condition reverses the process. Consider a system at temperature T in thermal contact with a thermal reservoir at same temperature. By an infinitesimal increase d T of the reservoir's temperature you get heat flowing to the body.
In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible.
