Which of the processes described below are irreversible?
Choose the correct alternative/s:
| (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 reservoir at a higher temperature \(T_2\) which increases the temperature of the gas. |
| (c) | A quasi-static isothermal expansion of an ideal gas in a 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 the compression of gas. |
