Isothermal Irreversible Expansion
Is it possible to have an isothermal IRREVERSIBLE expansion? I know that for an isothermal reversible expansion, work done on the surroundings is replaced by heat slowly. However, for an irreversible expansion, I know the expansion is fast but technically can it still be isothermal if enough heat is eventually given to the system to restore the energy lost by work?

Yes! absolutely. If the system expands fast, and the energy lost by work is replaced by heat, you can have an isothermal reversible expansion. Take in mind that, reversible expansion will do more work overall however (the area under the curve is larger).

You mean isothermal irreversible expansion right?
