Question

Consider a piston cylinder set-up. The maximum work is aimed for a compression process. The process must be entirely

-irreversible

-reversible

-adiabatic

-isothermal

-All of these

Answer 1

The irreversible compression process requires higher work input compared to the other processes. The adiabatic process could be reversible or irreversible (vague answer option). The isothermal process requires finite heat transfer which renders the process irreversible. Unless it is assumed that the isothermal process is reversible (also a vague answer option).
