An irreversible process is a [[thermodynamic]] process that results in an increase in [[entropy]]. Examples include the puncturing of a tire or the melting of ice.

In an irreversible process it is impossible to incrementally undo the changes and restore the original state with its original [[entropy]].

-An '''irreversible process''' is a process for which it is impossible to return both the system and its surroundings to its original state by reversing the process.  For instance, an internal combustion engine transforms hydrocarbon fuel such as ethanol into engine exhaust and energy; however, the engine exhaust and the energy transfered to the car cannot be transformed back into ethanol.  Irreversible processes generally involve an increase in [[entropy]].

 Causes of irreversible processes include friction, unrestrained fluid expansion, heat transfer, and mixing.
