Question

Reversible and Irreversible Processes

Answer 1

Reversible and Irreversible Processes

Reversible Process : A reversible process is one which can be retraced in the opposite direction.

A quasi-static isothermal expansion of an ideal gas in a cylinder fitted with a frictionless movable piston is an example of a reversible process.

Irreversible process : An irreversible process is one which cannot be retraced back in the opposite direction.

All spontaneous processes of nature are irreversible processes. e.g. transfer of heat from a hot body to a cold body, diffusion of gases, etc. are all irreversible processes.
