Matching isothermal processes with work expressions:
Reversible expansion: In a reversible isothermal expansion from 
to 
(where 
), the gas does work against external pressure equal to the surroundings. The work is 
, matching II.
Free expansion: The gas expands into a vacuum with no external pressure opposition. No work is done: 
, matching I.
Irreversible expansion: Isothermal expansion from 
to 
against constant external pressure 
. Work done is 
, matching III.
Irreversible compression: Isothermal compression from 
to 
(where 
) against constant external pressure. Work is 
, matching IV.
The correct pairings are A-II, B-I, C-III, D-IV.
