An ideal gas (fixed amount) undergoes an isothermal expansion from 10.0 bar to 1.0 bar either (1) re versibly, (2) against a non-zero constant external pressure, or ге- (3) freely against a vacuum. the values of the magnitude of the work obtained from these processes are eill in the question marks with equalities or inequalities (equals, less than, greater than).

more info ? ? i don't understand what the question is
