Which of the processes described below are irreversible? a) The increase in temperature of an iron rod by hammering it b) A gas in a small container at a temperature T_(1) is brought in contact with a big reseroir at a higher temperature T_(2) which increases the temperature of the gas c) A quasi-static isothermal expansion of an ideal gas in cylinder fitted with a frictionless piston d) An ideal gas is enclosed in a piston cylinder arrangement with adiabatic walls. A weight W is added to the piston, resulting in compression of gas
