Question

what do you mean by reversible or Irreversible process

Answer 1

Hey mate .......here is ur answer..
In a reversible process, at each point along the process path, the system is only slightly removed from being in thermodynamic equilibrium with its surroundings. ... For a reversible process, the system is ALWAYS in equilibrium with its surroundings. For an irreversible process, there will ALWAYS be an entropy change.
