In a cyclic process, the net heat transfer is always less than the net work done.
2
In a cyclic process, the net heat transfer is equal to the net work done.
3
In a cyclic process, the net work output can be equal to, greater than or less than the net heat input, depending on the efficiency of the process.
4
In a cyclic process, the net heat transfer is always greater than the net work done
