An irreversible process increases the total entropy of the system and its surroundings. The second law of thermodynamics can be used to determine whether a hypothetical process is reversible or not. Intuitively, a process is reversible if there is no dissipation. For example, Joule expansion is irreversible because initially the system is not ...
An irreversible process can be defined as a process in which the system and the surroundings do not return to their original condition once the process is initiated. Take an example of an automobile engine that has travelled a distance with the aid of fuel equal to an amount ‘x’.
Define reversible and irreversible processes. State the second law of thermodynamics via an irreversible process. Consider an ideal gas that is held in half of a thermally insulated container by a wall in the middle of the container. The other half of the container is under vacuum with no molecules inside.
14 Ιουν 2021 · We distinguish between two kinds of irreversible processes. A process that cannot occur under a given set of conditions is said to be an impossible process. A process that can occur, but does not do so reversibly, is called a possible process or a spontaneous process.
An irreversible process is a thermodynamic process that departs from equilibrium. In terms of pressure and volume, it occurs when the pressure (or the volume) of a system changes dramatically and instantaneously that the volume (or the pressure) do not have the time to reach equilibrium.
An irreversible process is a thermodynamic change that cannot be reversed without leaving a permanent change in the system and its surroundings. This means that the system cannot return to its original state after the process has occurred, often involving energy dissipation as heat or increased entropy.
Definition. An irreversible process is a type of thermodynamic change that cannot be undone without leaving a permanent alteration in the system or its surroundings. This means that once the process has occurred, the system cannot return to its original state without additional changes or input.
